Symptoms

Ubisoft Connect launches and syncs with the servers, then attempts to launch Anno 2205. Anno 2205 launches a window of blackout, which then closes itself in short order without any graphics display or audio. No exisiting recommended tinker launch steps resolve the issue.

Reproduction

Install Anno 2205. (on Ubuntu Studio 25.10) Press play.
