Updated Lightroom Classic

[David157F]

Updated Lightroom Classic this morning. Now getting an "Out of application memory" message on MacBook Pro using OS 10.15.5.  Message appears while using SlideShow module.  Activity monitor show Lightroom is using 135Gb of application memory.  Is there any thoughts as to the problem? Never had this error before.

When weird stuff like this happens, first thing to try is resetting preferences (can't hurt):
