I’m currently experiencing this issue as well, and deleting the RobloxStudio folder from the registry didn’t work in my case
This is the second time that an issue prevented me from using Studio:
This kind of problem is why I’m starting to loose interest in experimenting and developing with Studio. Other game engines tend to allow you to continue using a previous version if you experience any problems with their newest, and I strongly recommend Roblox to consider doing the same for Studio
I’m happy to report that Studio is now working again
