Ever since updating to LR Classic 15.4 i have been experiencing frequent freezes. Have to force quit LR and restart. I notice the ram is 70% absorbed.

Did that  also paused facial recognition, duplicate find, gps verification. Also changed  paging file settings. When it freezes RAM usaage was at 95%. Thanks

What mean “...LrC freezes…”? Does LrC crashed completly with an error message or crash report? Or do you see any activities → check in the Windows Task Manager.

What happened if you create a new and empty catalog, and then import several images?
