Looks like it's a media foundation issue. Game works with Proton-5.4-GE-3 and <Workaround removed by moderator>.
Hello @Corben78, that workaround is legally problematic and has been removed.
No more workarounds needed with Proton-5.5-GE-1

Symptoms
Uplay successfully installs and launches and synchronizes achievements and saves, but when Uplay tries to start the game the Starlink process either hangs or a popup with the following text occurs:
There is not enough memory available to run this program. Quit one or more programs, and then try again.As I've seen something about mfplat in the proton log, I tried the workaround to manually register and install media foundation, but nothing changed. Game also still has Denuvo active, which might be an issue.
