I Can't drag instances in explorer and i cant drag lines of code of script [SOLVED]

I’m having a strange error in roblox studio
It doesn’t let me drag instances and lines of code in script

I have tried to find a way to solve it, reinstalling Roblox Studio and more, but nothing has worked so far.
I have read that it has also happened to some people.

Any would be appreciated, thank you :smile: !

EDIT: Just restart your PC to fix the error!
