Short description of error
If I open a blender file I've been working on, my asset library is gone. The categories exist but no assets do.

Exact steps for others to reproduce the error
I opened a file containing various objects which I then added to a new asset library. Frequently tested the assets were saving by opening a fresh blender file every so often. Meanwhile I had another blender file open with my project scene in. I closed out my other blender file and went back to my project and refreshed the asset browser so I could scatter new assets into that scene. But all my assets are gone (including older assets that always opened fine), only the categories remain.

Attached the example file in case that helps.
