What the…
I guess the Studio file may have corrupted or something?
Can you please go to %localappdata%/Roblox/Versions and delete everything there. Then, reinstall Roblox studio (Roblox Studio Setup | Documentation - Roblox Creator Hub).
If that still doesn’t work, you can try just deleting the folder %localappdata%/Roblox. That may reset all your settings and stuff though.
uninstall roblox completely (delete all the versions) you can locate them in localappdata or right click > open file location on a shortcut on your desktop until it brings you to localappdata
