Bridge 14.0.1 Crashing Constantly

I ran into the same problem a couple of days ago and, after extensive bug-shooting, I am fairly confident that, in my case, this was due to the presence of a Script which interferes with Br 14.

There is a Script called Custom Metadata Panel which I downloaded from ACC and tried many years ago. 
It caused crashes and instability; and was not useful to me anyway; so I trashed it — or thought that I had. 
Apparently I had not done this thoroughly enough because that Script reappeared when I re-edited my older NEFs.
I could not get rid of it but found an updated plug-in version on ACC and installed it; then trashed it (its only usable under Rosetta); and that finally seems to have cleared the Script out of my computer.
The result is that I am no longer getting the Bridge PR freeze-ups which were plaguing me previously.
 
I am updating older NEFs to the newest build of ACR  and acknowledge that these are very large folders which may contain over 5000 RAW NEFs; and that I am working on folders that are located on a HD across a WiFi connection; but there was definitely some malfunctioning with Br 14.
(This is on Mac OS 14.2.1 Sonoma).

Since I removed all traces of "Custom Metadata Panel", I have not had a single freeze or crash of Br 14 for over two days.
 
Others who experience slow preview-building and frequent crashes and freezes might want to check their Scripts to see if the Custom Metadata Panel (or any other add-on Script) is present; and see if disabling those Scripts cures their problems.
