I get a white screen when trying to upload custom SDK packages.

Hi. When I first downloaded and installed unity, I was getting a white screen when I created a new project, like this Screenshot by Lightshot

Somehow I fixed that and now i’m getting a white screen like this Screenshot by Lightshot when trying to import custom SDK Packages, does anyone have experience with this and know a fix?

nvm this Screenshot by Lightshot keeps coming back!
I’ve tried deleting the project folder, library folder and the Unity folders in %appdata%
I’ve also reinstalled several times…
