I have a problem with the game, when I want to make a car or in the campaign,car bodies or engines do not appear in the game, so I can’t do anything.
Have you tried reinstalling the game? Verifying files on steam?
It looks like it might not be able to write to the database file so check that its all in the same place and not in external drives etc and check permissions.
Try to verify your game files, there are probably missing files.
Disable controlled folder access if it is enabled. This happened to me a while back, and the screenshots mirror perfectly what I encountered with this feature enabled, so either disable it completely or allow the AutomationGame app through controlled folder access.
