I'm running Manjaro (Arch derivative) and was getting the same "Browser Crashed" error with a Lutris install.
I was already using DXVK v1.10.2 and NVidia 515.57 -- but switching to lutris-fshack-7.2-x86_64 made it work for me.
Important: reboot after switching to the new version of Wine. When I switched back to lutris-GE-proton7-1-x86_64 to get the error name, going back to fshack version didn't work until I rebooted. (Initial change to fshack 7.2 was part of a big update release on Manjaro, so it had a reboot.)
Only problem I've seen is that in some scenes with strong light sources (like campfires or large torches) the brightness / darkness jumps a lot depending on how occluded the light source is -- it wasn't a problem with GE Proton 7.1.
