Anything in the log?

Make sure the game's executable (I assume it's not called MarsSteam.exe?) is in the exceptions list/whitelist of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.

Thanks for finding that! I haven't yet got my own copy on this platform.

From that log I'm pretty sure this is a bug, and I see we now have another report in this forum.

@Azurespecter is this something you can pick up and run with?
