Bug: Switched to Rhino 8 and lost all default settings in Rhino 7

Hello,

I switched over to the Beta version of Rhino 8, but when I opened it while I had Rhino 7 open, it looks like somehow Rhino 7 reset to all of the default settings, so I lost all of my UI customizations and aliases. Is there a way to recover these?

Best,
Paul
