Ah got it. The python apps from AUR require the rebuild for the new python on the system.
I havenât come across it myself, but I suppose it can happen that the AUR package isnât ready for the new version of python?
I suppose that is when users start looking at python virtual environments?
Thank you banjo, that work-around works perfectly 
Overlay packages have been built by Manjaro Team.
Sync packages are taken as they were from Arch.
No.
ĂUR packages are built locally against the then installed versions of other packages/libs (python in this case) when installed.
They (oftentimes) need to be rebuilt, when those libs get updated.
Sometimes one gets away without rebuilding and the AUR package just seems to work - but if any âsuspiciousâ malfunctioning starts happening itâs a good idea to first freshly rebuild the AUR package in question.
Sometimes these packages wonât work at all without rebuilding - as is the case with these python packages.
Everything seems to be fine on cinnamon.
It looks like you are on Testing branch?
But to answer your question, use Pamac to upgrade.
Hello, I fixed my issue with nvidia 340-xx.
Tnx for the info, but I also had some error 2 thing 
Since I was on kernel 5.10.41-1 fallback initramfs wich was compiled with 11.1 gcc according to inxi -Sazy and kernel 5.4.123 was completely unusable, I decided to uninstall and install again.
So I uninstalled kernel 5.4.123 and the headers as well and installed it again.
linux54 and linux54-headers
It worked!! without any errors!! I did that through pamac its easier.
So first would be to try to boot to a fallback if it works or install another kernel through
tty CTRL + Alt + F3
If all goes well you boot to that kernel and again uninstall k 5.10.41-1 and install again.
linux510 and linux510-headers
If all goes well you can boot to k 5.10.41-1 and enjoy
This worked for me.
@6x12 tagging you in case you havenât solved yet.
I still canât launch certain things including my terminal, so I have to use uxterm but I have also lost copy/paste.
I still get this error when trying to run urxvt:
error while loading shared libraries: libperl.so: cannot open shared object file: No such file or directory.
I have updated the perl modules using 
pacman -Qo /usr/lib/perl5/5.32 as suggested by @freggel.doe and everything played nicley.
I have also done done this as suggested by @philm in reply to @stargazer :
# Install yay
sudo pacman -S --needed --noconfirm yay
# Rebuild AUR python packages
yay -S --noconfirm $(pacman -Qqo "/usr/lib/python3.8/site-packages")
Still not working.
Any suggestions as what to try next?
Thnx.
Thanks but that doesnât seem to work for me still get the dkms error (make.log showing gcc mismatch) when reinstalling linux54.
Hi,
First uninstall k 5.4 again, add export IGNORE_CC_MISMATCH=1 to /etc/profile or to /etc/environment it should work either way and try againâŚ
The thing is to make the kernel and nvidia to be compiled by the same version of gcc.
No, doesnât work for me.
Removed linux54 and linux54-headers with pamac, added
export IGNORE_CC_MISMATCH=1
line to /etc/environment file (it was already on the bottom of profile file) and reinstalled linux54 (5.4.123-1) and linux54-headers (5.4.123-1) with pamac but still getting the same error.
Can you open a separate thread and post inxi -SGazy, pacman -Q gcc and /var/lib/dkms/nvidia/340.108/5.10.41-1-MANJARO/x86_64/log/make.log
just the first 15 -20 lines ??
So more people can get involved and try to help.
This is weird to say at leastâŚ
Can anybody please advise on the best way to perform this latest update while staying on the 460.73.01-3 nVidia driver? Last stable update, I tried to update with all the nvidia related packages added to the pacman.conf ignore list, but my system wouldnât start and gave a module error of some kind (canât remember specifically). I had to add all the following to be ignored in â/etc/pacman.confâ in order to boot whilst still updating; lib32-libvdpau lib32-nvidia-utils libvdpau linux54-nvidia mhwd-nvidia mhwd-nvidia-390xx nvidia-utils xf86-video-nouveau linux-firmware linux54 linux54-virtualbox-host-modules virtualbox.
Is there anyway to update the kernel related packages, but not the nvidia ones, without breaking anything on this update? I canât yet update to the later nVidia driver(s) and require to stay on the current functional 460.73.01-3 driver for the time being, until nVidia come up with a genuine solution.
Apologies if this is not the relevant place to ask to ask.
I finally got a chance to download and fire up a live session with the 21.0.6 ISO and I still have the same graphical glitches. It seems some regression has appeared that only affects my graphic card (AMD R9) and others similar to it. The glitchy graphics (it seems to affect mostly text in programs that use OpenGL) began after upgrade from mesa 21.0.3 to 21.1.0. I have reached mesa 21.1.2 and it seems it still hasnât been fixed upstream. I would downgrade back to 21.0.3 but when I do that my plasma session doesnât start anymore.

Iâm in the same boat too.
Iâm currently using an old btrfs snapshot that has the nVidia 460.73 driver working correctly with kernel 5.10 and Iâm not keen on updating at all just now as the nVidia problem is still persisting with the current driver I believe. Like you I tried ignoring the nVidia stuff and updated but still had a problem. I have âquietâ off in Grub as I like to see whatâs happening as the system boots but it ends on something like ânVidia magicâ versions not matching. Sometimes I can switch to another tty to reboot. Subsequently allowing the nVidia driver to update still caused the same issue.
I the tried switching to the Nouveau driver but the performance on my old system with my 4k TV was just about hopeless (very sluggish graphics). I then reverted to the btrfs snapshot (very quick and easy to do with grub-btrfs).
Hi,
Iâm getting this when updating:

Nvidia. I was hoping that with this latest Manjaro update the Nvidia driver update would have been reversed.
I am holding back on updating as I see so many troubles with Nvidia. I have chosen Manjaro Stable as I read so many positive things plus I just donât have the time and patience anymore to repair broken systems.
How do I know when this unstable nvidia driver matches with Manjaro Stable?
Very hesistant on updating.

Hello. I am experiencing problems with my bluetooth headset since I updated. I use Sony WX1000xm3 and before I wasnât experiencing any issue.
Right now when I connect them they reproduce the microphone input and not what the computer is playing.
I use Gnome.
Check the âOutput profileâ setting in the Sound settings and adjust to A2DP. (playback)
