Windows 11. Everything up to date. Other Unity games work.
Event Viewer reported: Fault Bucket, type 5. RADAR_PRE_LEAK_64. With the Problem Signature P1 being the exe. (I gather from googling it this means: The game launched and shouldn't be an issue)
All in all it seems like a corrupt file (possibly unrelated to starmaker). Though re-downloading does not fix the issue. It's strange that this problem has happened twice on separate machines without any shared components from either; and only after installing a new version of the game.
(I'm trying to figure out how to get better log info, but I'm rather slow with this stuff)
