Lightroom Classic shows error when deleting a photo while zooming

I'm not able to reproduce this on my LR 13.0.2 / Windows 11. So either there are particular steps you're taking different from my what I'm doing, or there is something particular to your installation causing the problem.

Some next troubleshooting steps:

1. Restart your computer.

2. If the problem persists, 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.

3. Do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

• What plug-ins do you have installed?
• Oh, you stated Delete key, and you are on a Windows computer, not a MAC, what if you use the backspace key it the DEL key?
• Does this also occur if you use the existing option to Remove the photo (as opposed to using the DEL key)
• Does this also occur if you press on the X key as to reject (as opposed to actually deleting)
