My studio is having problems

So, i only opened up a game and then my scrolling wheel doesn’t work while developing. The scrolling wheel works in game testing.

→ I tried restarting the studio app
→ I tried uninstalling the studio and then reinstalling it.

This only happens on that game, when i try that on other game, it works.

Btw, that game has no elements inside the StarterGui

I also downloaded a copy of that game, and the scrolling wheel works on the copy for some reasons.

Now it’s happening to the published games with same map as that game i abandoned

Update: It was terrain problem which was causing the problem to spread.
