I'm having a similar problem. In my experience it's completely NORMAL for new versions of Photoshop and After Effects to crash, hang, etc. but Bridge usually performs relatively okay. Not this time. It hangs, especially when I quickly navigate back and forth between folders. It looks like the app can't keep up. This can take 10 sec or a minute before it unfreezes. I usually just terminate the application and restart.
I'm on Win 10
Bridge verison 18.104.22.168
The extra time these issues with Adobe apps take -every time there's an update that 'fixes instability issues' - remains shockingly high compared to any other software I use, ever.
I shouldn't have to do 'maintanance' after an update.. The update should be the maintanance.
