I’m finding that every time I open asset store from within unity all I see is a blank screen. I’ve tried re-installing unity and the problem still occurs.
Managed to find a workaround to this problem. As I said I tried a re-install but that still didn’t work. But, then I tried uninstalling and also deleting the registry keys (which you can find in this answer: Total remove and re-install - Unity Answers) then it worked again.
