188.8.131.52 on Big Sur will not display thumbnail images and freezes. I have to force quit to make it go away. Seems to have just started doing this. Haven't opened the program in as long as a week. But definitely a problem this morning.
Please try rebuilding your Bridge's Preferences
Rebuild Bringe’s Prefs
First, quit Bridge (if open). Then, when launching Bridge, press Command-Option (Mac)/Control-Alt (Win) + Shift to choose “Reset Preferences”, Purge Entire Thumbnail Cache”, and/or Reset Standard Workspaces.” In your case, chose "Reset Preferences."
Before getting your response I uninstalled and reinstalled Bridge. Didn't have a chance to open it till now and it seems OK. Hopefully it doesn't crash again, which it did three times earlier today. Thanks again!
