From my post on the forum:

I was on the phone with another user and he had no problem getting the new Library Dialog to pop up. But I was still having issue with the Fresh Install as well as the non-networked installations (the ones we really use). So while I was on the phone, I signed in to Altium using the fresh install - but DID NOT connect to any 365 workspace. It worked. Then I signed back out and closed it out. Reopened the fresh install and again it hung. So Task killed it and reopened it. I then signed in again - and again, not to any 365 workspace. It popped up the newfangled library dialog. So i signed back out, closed Altium. BUT this time when I reopened Altium AND DID NOT sign in I DID get the pop up library thing. Tried again, closed out Altium, reopened Altium, did the the File - New - Library... and AGAIN I got the new dialog. So now I'm wondering WTF?.
So I uninstall that fresh install. Totally. I then re-install another fresh install to a totally different location. Open up this new, fresh install - No Prefs - just my ALF file. I close back out
Guess what? I reopen - DON'T SIGN IN - and now this new install hangs/crashes on doing the File - New - Library... Try again - same thing.
This is nutz...
Software totally hose the old adage that doing the same thing over and over again and expecting different results is insane.
Nope - just buggy software...
