Hello,
I believe this is the place where I was told to open this issue.
The lastest HoYoPlay lancher (by Hoyoverse) will crash every few seconds when running under proton. After opening an issue there, it appears that this is a driver issue.
Please see: HoYoPlay · Issue #7951 · ValveSoftware/Proton · GitHub
Please let me know if there is any additional information needed not already mentioned in that issue.
Thank you
