Cider - AM login issues

Hey there, I haven't listened to music on my computer for a while and when I opened up Cider yesterday, I noticed it signed out of Apple Music. When I tried to log back in, an empty web page (about:blank) opens up but nothing else... When I close that windows, the same window pops up again, going into an endless cycle...

I uninstalled and reinstalled Cider but it didn't fix that either. Has anyone had a similar experience recently?
