Cannot properly load catalogs, LR crashes

When I open a Lightroom catalog in LR classic (version 15.3.1), the histograms and 1:1 previews of the images won't load. When I try to do anything, Lightroom will freeze and crash and I'll have to force quit. I’m using a Macbook Pro updated to Tahoe 26.5.1, I've cleared video and RAW caches, cleared preferences, shut off GPU, checked the integrity of the catalogs, optimized them, uninstalled and reinstalled LR, and restarted my computer.
