Reproduction

From proton log i can find

4298.365:002e:002f:err:esync:esync_init Failed to open esync shared memory file; make sure no stale wineserver instances are running without WINEESYNC.

Disabling esync fixes that. It worked out of the box with Proton 4.20-GE-1

@GloriousEggroll This happens to me too if using the latest release, and is fixed in the same way by disabling esync

closing, this was not caused by esync, and has been resolved with reverting a different change that was made.

Doom Eternal not work with Proton-6.1-GE-1 Hotfix [x].
With Proton-6.0-GE-1 work fine.
