When I start the game through Galaxy it onely gets dark for a second then nothing happens. What could be the problem?
In the description it says the game sould run on win 11 but the last update in the changelog says it now runs on win 10...

Started up just fine for me, but there's a black box around the icon. Researching.... Win 11, newest official build for home outlets August 2025.

EDIT 2: Official page gives a malware warning on download. Here is the wiki page, with the latest Developer Snapshot being from 2023 as of this post - fixed my issues.
