I was using roblox studio with no problems (as long as possible, since it’s roblox studio) and I closed it, and when I tried opening again it got stuck in a empty loading window, forever.
I tried restarting my computer, reinstalling the studio, loading default settings, disabling beta features, deleting every roblox’s registers and nothing worked.
if it’s a corrupted file you need to hard re-install Roblox for it to work. Type %appdata% in your search bar —> Local —> Roblox(folder) and when you see that folder for Roblox, give it a good ol’ deletion and when you try to open studio or roblox again it forces your roblox to have all new files. Hope this helps!
