Open a support thread for your issue.
HI, you should create a new own thread in the Support category.
You will have a good visibility and some expert will certainly give you support. 
If youāre able to boot from 5.10 and remove custom scripts into grub, just do it, a few days ago I has the same issue.
I just wanted to point out that the Manjaro theme for rEFInd is gone after the update 
https://discover.manjaro.org/packages/refind-theme-maia
Pamac says that it canāt find this package.
Edit: Looks like it is still under /boot/EFI/refind/
Ok, Iām going to do it, thank you for your suggestions, gan and omano.
Are you talking about /etc/default/grub or about other configuration files and scripts?
A small problem after this update (Xfce). I needed to log into my session in LightDm in Qwerty, my French Azerty keyboard layout was gone, including in the session. I had to reconfirm it in manjaro-settings-manager.
But all was fine on my other box (KDE).
the other minor issue i noticed is that eevery time I reboot my volume is always muted and I have to unmute.
Update went more or less without issue, after I removed kwin-lowlatency and installed normal one. However, I am not able to access the Compositor settings nowā¦
I am getting this when I run systemsettings5 through terminal:
kf.kcmutils: This module has no valid entry symbol at all. The reason could be that itās still using K_EXPORT_COMPONENT_FACTORY with a custom X-KDE-FactoryName which is not supported anymore
EDIT: This is how to fix it:
sudo rm /usr/local/share/kservices5/kwincompositing.desktop
I also replaced the -git versions with the regular version like so: sudo pacman -S --nodeps lib32-mesa mesa. Then I could update as usual.
Iāve been thinking, I probably switched to mesa-git when Cyberpunk 2077 came out and you needed to update mesa to mesa-git in order to play it straight away.
Everything is a-okay now

You donāt have to restart the OS necessarily, you could just restart plasma for example with
kquitapp5 plasmashell ; sleep 2 ; kstart5 plasmashell > /dev/null 2>&1
or
DISPLAY=:0 plasmashell --replace > /dev/null 2>&1 & (assuming your display is on 0)
Thereās a nasty rendering problem in KDE with my 2-monitor system. Described in more detail in the KDE Plasma section:

Thanks Manjaro team for all your hard work you put into making every update.
5.10, Gnome, nvidia proprietary drivers is working great. updated to 5.11 kernel and everything seems to be working fine.
As a side note that doesnāt really have to do with this particular update (not sure which update I started having the issue) but I was having issues with when I started wine games (like world of warcraft or Skyrim SE) I would get the dialog box stating that the application isnāt responding which if I clicked wait it would then proceed normally. After doing a little research I found that this was controlled by mutter many people had this issue so they made the timeout value configurable now. The default timeout is 5s, I bumped it up to 15s and now all my games launch fine.
The solution for this is to run this from the terminal:
gsettings set org.gnome.mutter check-alive-timeout 15000
(the value is in milliseconds so my example here would set it to 15 seconds, maybe overkill but I just donāt want to see that dialog box and I still got it for skyrim occasionally when I set it to 10 seconds lol, the default value is 5000 or 5 seconds.
I noticed that after updating to 5.11 my AMD GPU was getting very hot. It turned out that the GPU fan wasnāt running at all. I downgraded to 5.10 and the fan runs. Same with 5.9 - fan runs. I uninstalled 5.11 then reinstalled it, but the fan still doesnāt run. Iām staying on 5.10 for now.
All fine operation -wise, but I notice that On the KDE system settings the āAppearanceā category has been left out in the cold!
Which AMD GPU do you use?
Some AMD GPUs have āZero Noiseā Features.

Itās an RX550.
Everything is fine except the icons in my KDE system tray seem to be much more blurry now. libappindicator-gtk3 seems to be installed as per the arch linux wikiās recommendations. Not sure what happened.
