Always pay attention to the announcements wiki. Your issue is related to this:

Nvidia 495xx driver series drops Kepler support; need to manually switch to 470xx.

mhwd’s video-nvidia now provides 495xx; if you need 470xx you must manually switch before updating, by using the commands below.

With the new 495xx driver series a lot of Wayland adjustments got added. Also Nvidia decided to remove Kepler support . Therefore you may want to switch drivers to 470xx series, which still supports those graphic cards:

sudo mhwd -r pci video-nvidia
sudo mhwd -i pci video-nvidia-470xx

Nvidia 340xx driver series no longer works.

This driver is end of life by NVIDIA, you should not be using it as there are serious security issues with this driver. You have to either get newer supported hardware or switch to Nouveau:

#remove old
sudo mhwd -r pci video-nvidia-340xx
sudo mhwd -r pci video-linux
#install new nouveau
sudo mhwd -i pci video-linux

Reboot after and you're done.

So, check what compatibility is with your dGPU and install the proper drivers.
