Photoshop Elements 2026 Organizer makes Windows File Explorer very slow

Whenever PSE 2026 Organizer is running, Windows File Explorer becomes very slow.  In addition, any file operations done withing Organizer (such as right-clicking a photo, and selecting Copy) become painfully slow (15-20 seconds to complete).

I’ve done experiments where I have Organizer running, but idle.  Watching the Task Manager, Organizer is using very little CPU (<1%).  In File Explorer, I double-click a folder which has nothing to do with PSE, and Organizer’s CPU jumps to 25%, and File Explorer stops responding for 10-15 seconds.   I wait for Organizer’s CPU to return to idle (5-10 more seconds), then double-click another folder in File Explorer, and the same thing happens.  If Organizer isn’t running, File Explorer response is near-instant.  

I’ve set Organizer to not watch any folders.  I’ve seen other threads about conflicts with Anti-Virus software, but this is Organizer using up system resources, not my AV software.

Why is Organizer “waking up” and doing something fairly intensive any time I try to use File Explorer?

I am running PSE 26.3.  OS is Win11, current version.  Intel Core i9-11900, 32 GB RAM, NVidia GEForce RTX3060.  Plenty of free space on OS drive and Data drive.
