My game randomly broke

So as you can see in the video whenever i destroy a rock or kill an enemy some of the dropped tools fall through the map. This just randomly started happening today for no reason. No changes to the scripts, no errors. Is there some kind of studio bug or?

I want to try and reinstall studio to see if that fixes the issue but im afraid ill lose all of my tool box models.

it might be part of a script?
You wont lose your toolbox models because it is a part of your account.

The scripts were working fine for weeks though. No errors in output. the only odd thing in he output is the stack end () number just keeps rapidly going up whenever the bug happens.
