Preview not changing when toggling between files

[ahill59]

I'm running LR Classic, ver 11.2 on a MacBook Pro M1, Monterey 12.2.1, 16gb RAM.  I import and build Embedded + Sidecar previews.  I select my photos by toggling from image to image with my right and left arrow keys to determine which exposure is best, but the preview in Library mode (D) doesn't change.  I can see the selection change from the filmstrip below, but the full screen image does not change.  Sometimes it takes 3-4 toggles back and forth before the image I select is shown.  I have deleted and reloaded LR but the problem persists.  Any ideas are appreciated.

Try resetting LR's preferences:

LR sometimes soils its preferences file, and resetting it can fix all sorts of wonky behavior. That article explains how to restore the old preferences if resetting doesn't help.

This happened to me yesterday too.
