Cant open games in version history, error 409

I was working on a game with my friend when i ungrouped something and some stuff started to look weird:


I tired undoing but it didn’t work, so i decided to go to game history but this error showed up

what i think caused it:
I might have added a virus into the game by accident.
I ungrouped a model then it happened (probably not the direct cause)

i tried

  • closing studio
  • turning off collaboration then signing out
  • looking at the dev form

I don’t know what to next so i wrote this. Any help is appreciated. If you need more details i’ll respond to you.

You might have to call roblox support (they are terrible at their job)

i disabled team create and my friend copied and pasted the map into a new game
