Symptoms

Uplay doesn't launch. In my system monitor I can see, that it's trying to launch Far Cry 5. The process then quits and a process called UplayCrashReporter is created and quits shortly after. During the whole time, the UI of Uplay doesn't show up. According to Steam the game is running the whole time and won't quit, until I kill the processes.
EDIT: After download Proton 3.16 Beta through Steam/Library/Tools Uplay is now working, but Far Cry 5 still isn't working.

Uplay works with vanilla wine. It also works with this variant of Proton: https://github.com/kakra/wine-proton . However, Far Cry 5 still won't launch. I get a popup from Uplay that Far Cry 5 is being launched, but nothing happens.

Reproduction

Download and start the game.

Start with the linked system-information Gist and the manually downloaded Proton log, then reproduce by downloading and starting Far Cry 5 (Steam AppID 552520) on the listed Radeon VII, Mesa, and kernel setup. Done means identifying why the game fails to launch and recording a verified compatibility result.
