Lightroom locks up when syncing catalog

[aegeiger]

I have a catalog set up but it didn't import all of the photos initially, so I'm trying to sync the catalog (Library module) to import the remaining images. Every time I do, it locks up and I have to force quit. I'm using a 2019 MBP with OS 12.3.1. i9 processor, 32gb RAM, AMD Radeon Pro 5500M 8 GB graphics card, 1 TB HD space available on the laptop. Both catalog and images are on the laptop itself. Using LR CC 11.3.1, but also tried previous version. I optimized the catalog, turned GPU off in LR, cleared cache. I've attached the generated error report. Anything I can try?

Try resetting your Lightroom preferences:

Quit Lightroom Classic.
MacOS: Press and hold the Shift + Option keys.
Windows: Press and hold the Shift + Alt keys.
While holding down the keys, launch Lightroom Classic.
When asked, select "Yes".
