Are you running it with EasyAntiCheat enabled? When I had an issue with the same behavior (white screen, custom cursor, then crash) EAC wasn't initializing properly. If i recall correctly, I reinstalled the proton EAC runtime on Steam to fix it.
Also as another commenter said, don't expect great performance with that GPU. While I was still using a 1080ti at Elden Ring's launch I got around 35-45fps at 1440p, while easily hitting 60 on Windows.
