serious issues with blank preview icons that affects Materials, models, and prefabs
Materials can be fixed by right clicking and refresh, which wipes them of all their texture links, but then
CTRL+Z then remaps them, until the editor flashes and wipes the previews again.
However for prefabs iv got no fix.
Iv done the following:
Deleted Library - Restarted
Deleted Artifacts - Restarted
Copied to new project same version
Upgraded to new version 17 → 18 same issue repeated steps again - no fix
I did however find these in the console window after setting everything to debug mode:

As well as this:

Iv got hundreds of kitbash prefabs I NEED to be able to see and materials, or i’ll never get anything done. How do I fix this Unity Devs?
