JPG , PNG icons not showing in After Effect

I’m having a strange issue in After Effects. My PNG files are importing correctly, but in the Project panel the PNG icons don’t show — they appear as blank/white file icons (screenshot attached). Compositions show normally, but PNG thumbnails are gone.

I’ve tried:

• Restarting AE

• Clearing cache

• Re-importing PNGs

• Resetting preferences

• Updating AE

The PNGs work fine on the timeline — only the icons in the Project panel are missing.
Has anyone experienced this or knows how to fix it?

Thanks!
