I know you have an adguard, but have you thought about ditching those and using pinhole+unbound?

Have you considered using Heroic game launcher instead. I think its good as long as you use wine fixes instead of proton ones.

Edit: looks like lutris is installed but corrupted?

What about this command in terminal.

dpkg -l | grep -i lutris

You could go down the GPU Passthrough option to a VM. If you have integrated and and another GPU you could use LookingGlass and never even have to leave the Linux instance. Single passthrough is what i use to run Gamepass as you do get some good games Day one.
