P: Library Previews not updating

Allowing LRC full Disk Access seems to solve a lot of "problems". If you install other applications, like 1 Password or Techtool Pro, you have to allow Full Disk Access to those also... There just seem to be more steps to installing software applications than a long long time ago !

For anyone reading this, just went through support and a remote session. I had to go to system prefs/ security and privacy/ accessibility then add LR CC to that option, then in the same window add LRCC to "full disk access" and "Files and folders". The agent then reflashed the lightroom main preference file (but i cant remember where that file was sorry)

LRCC 14.4.1

So I've followed the various "fixes" including signing out, and my previews in library mode are still not updating after syncing edits or using a quick develop preset. 

Thumbnail preview at the bottom appears to be also performing better after a crop. There seems to be some improvement in the scheduling of the update. Seems to be more immediate. Not just crop, other adjustments are being updated in the thumbnails.

Hi Rikk. The answer to having the Navigator Panel opened is yes. There is a performance improvement when the panel is opened. Close the panel with the disclosure panel button and it no longer syncs. Re-open the panel and it is responding almost live to the crop resize.

That would be a viable workaround for the Crop Issue. 

What isn't clear to me is: Is the Preview not updating (ignoring crop) being encountered any longer?

"Does the Crop Update on the Library Preview if you have the Navigator Panel Open? Does it make any difference whether that panel is open or closed?"

In my LR 11.4, when the Navigator panel is open, the Secondary Display > Loupe - Normal and the filmstrip thumbnail update correctly as I adjust the crop.  If I start out with the Navigator panel closed, then as soon as I open the panel, the stale Loupe - Normal and thumbnail catch up.

LR generally releases about every 8 weeks.  So if history is any guide, we'd expect to see LR 11.5 in the next 8 weeks or so, which one hopes will fix the issue.

Meanwhile, try reverting to 11.2. I learned this from Adobe pros. Although maybe LR 6 will be more stable.

Here a screen recording of my LR 11.4 / Mac OS 12.4, showing the filmstrip thumbnail and Secondary Display > Loupe - Normal not reflecting the current crop in Develop, as described by @dw24154351:
