TIFF image has been taking over 5 minutes with no movement on the progress bar

After updating my catalog from Lightroom Classic V12 to V14.0.1, it now runs ridiculously slow to the point where it's practically unusable.  I've escalated this to Adobe tech support and did an hour plus support session (case #ADB-36901627-L0Q7), but they were unsuccessful in fixing the issue.

I sent Adobe support my existing catalog and they confirmed that there is nothing wrong with the catalog (ie: not corrupt).  I even imported my entire catalog into a *brand new* catalog and the problem is persisting.  My computer has exceeeds the specs but simle actions lag and literally take minutes for LR to catch up (system specs below).

Some examples of the problem:

• Importing ONE TIFF image has been taking over 5 minutes with no movement on the progress bar (screen grab attached).

• Setting star ratings on a selection of 10 images takes almost a minute.

• Quitting lightroom, the system sporadically stalls and doesn't quit for over a minute.

• Etc.

I've run diagnostics on my computer hard drive and there are no problems there either.  This is happening on my second computer as well.
