Maybe an issue with the ™ in the path? wine: could not open working directory L"Z:\\home\\doggo\\.local\\share\\Steam\\steamapps\\common\\EVERSPACEb\0004\" 2 - Demo Prototype\\", starting in the Windows directory.
It took some tries and the first one was glitching the Steam client as hell, but seems to be working fine.
Arch Linux. Proton 5 (next). AMD 5700XT. Mesa 20.2

PD: For both this and the GhostRunner demo, it starts on Fullscreen with like 1FPS, and I have to Alt+Enter to go to window mode and then runs fine, and Alt+Enter again to go fullscreen and then both play nicely.
PD2: Could play without any problem
