How do you uninstall the 60gb of residual files? It has glitched perms PC

After uninstall, the file leaves a mess of excess and you dont have the perms to correct it for whatever reason. And if you try and reinstall it—woof. That's 130gbs on your pc. I'm lucky that wasn't me but I still want to know what I need to do.

well i uninstalled and waiting for a better launcher. this launcher is trash

That's what I plan to do.

No point trying to install if if it's just going to freak out and redownload itself multiple times.
