System Information
Operating system: Ubuntu 22.04.1
Graphics card: NVIDIA GeForce GTX 1070 Ti

Blender Version
Broken: version: 3.5.0 Alpha
Worked: Latest 3.4
Caused by 1efc94bb2f

Short description of error
Libraries disappear after refresh button is pressed.
Terminal shows "can't find .blend"

Exact steps for others to reproduce the error

Create asset library and assign correct path in preferences > File path > Asset libraries
Open asset browser and select asset library
Click "Refresh" the entire library disappears.
Load factory settings doesn't fix the problem.

The follow video shows the problem better tan 1000 words.

More info:
I've run this command to check the libs intetegrity... and looks fine

import bpy
from pathlib import Path

prefs = bpy.context.preferences
filepaths = prefs.filepaths
asset_libraries = filepaths.asset_libraries

for asset_library in asset_libraries:

  library_name = asset_library.name
  library_path = Path(asset_library.path)
  blend_files = [fp for fp in library_path.glob("**/*.blend") if fp.is_file()]
  print(f"Checking the content of library '{library_name}' :")
  for blend_file in blend_files:
      with bpy.data.libraries.load(str(blend_file), assets_only=True) as (file_contents, _):
          print(file_contents.node_groups)

Looks like a regression on quick testing. Will check again.

If I clean cache directory the files appear again, but only for 1 time!

It's not clear to me how to reproduce this issue. The file in the video seems to be saved already into the directory that is later used as asset library, but it's not clear to me in what state it is, e.g. if the asset is already stored (and thus tracked by the asset index/cache) in there or not. The banner hides the title bar which contains interesting information.

From the video it seems weird that something is made an asset in the current file but doesn't show up in the Current File asset library. That definitely seems wrong.
Could somebody provide clear steps to reproduce this starting with factory settings?

@JulianEisel hi, you probably could have been able to relate the video with original description. But I later edited and added the steps to redo the bug from scratch.
Let me know whether the attached video is helpful.

To reproduce this on my installation (see the #102624) I follow these steps:

Open any blend file from the MyAsset library folder. Say /data/mylib/baseball.blend.

Assets editor/CurrentFile/All: Correctly shows the baseball Collection (which is marked as asset).
Assets editor/MyAssets/All: Also correctly shows the same baseball Collection. But no other assets from the same library.

Select the Assets editor/MyAssets and Hit the Refresh Asset Library.

Correctly refreshes the bassebal assets (i.e. no change). The asset won't disappear here.
The other existing assets from other blend files in the /data/mylib still won't show up.

Save the file (make any negligible change).
Main menu /File/New/General:

Assets editor/MyAssets/All: Still correctly shows the baseball asset. But only if the file in 3) was saved. I.e. it is no enough to just open the baseball.blend file.

Press Assets editor/Refresh. Or just change to Current File and back to MyAssets

The baseball asset disappears.

4b) Close Blender. Open new Blender instance. New/General.

Assets editor/MyAssets/All: baseball asset not shown.

I guess all action in 4) 5) and 4b) somehow trigger asset library refresh.

To reproduce this on my installation (see the #102624) I follow these steps: 1) Open any blend file from the `MyAsset` library folder. Say `/data/mylib/baseball.blend`. - `Assets editor/CurrentFile/All`: Correctly shows the baseball Collection (which is marked as asset). - `Assets editor/MyAssets/All`: Also correctly shows the same baseball Collection. But no other assets from the same library. 2) Select the `Assets editor/MyAssets` and Hit the `Refresh Asset Library`. - Correctly refreshes the bassebal assets (i.e. no change).

While I can't recreate the appearing and disappearing of assets as seen in the video, I did notice that assets started not showing up for me anymore. Turns out that after {1efc94bb2f7b}, the asset indexing would be broken, and basically just create empty files when it would update or create information for a .blend.
So to recreate that you can just re-save a file in an asset library with current master to force an update to the index. Its assets will not show up anymore from external files.

Disabling the asset index (enable {nav Preferences > Interface > Developer Extras} and disable {nav Preferences > Experimental > Asset Indexing}) should bring the assets back, but with slow load times.

Now, I have a fix ready for the creation of empty index files, however we need to somehow enforce updating the already created empty index files. Need to figure out a nice way to do this efficiently.

Hi Julian, thanks for help us!

"Disabling the asset index (enable Preferences → Interface → Developer Extras and disable Preferences → Experimental → Asset Indexing) should bring the assets back, but with slow load times."

It works, but it is a little bit slower, you're right. We can deal with it.
Tell me please if you want more information, I would send you!

6a7917162c and 1229b96652 are committed now, so the indexing can safely be enabled again.
