You shouldn’t have to install this. Reinstall studio itself or run in administrator mode which sometimes helps. I just updated studio and got no issues.
its fixed now. just have to run it by admin every time. i dont know what fixed it, its still junky.
Sometimes the easiest solutions are the simplest ones.
Try to remove Roblox folder from Program Files(x86) and launch studio from AppData. It’s helped to me. Also if you updated studio as Admin you can run RobloxStudioBeta and skip part of giving admin perms
It happened to me once, and the reason was very weird. It was because I had a warning I didn’t see on the website. So instead of studio saying I have a warning, it says WebView2 isn’t installed. So cool.
