Short description of error
Ctrl+Z'ing after appending certain collections through the asset browser can cause a crash. Notably, the behavior between appending through the asset browser differs from using File > Append.

Exact steps for others to reproduce the error

Download attached blend file and save it to an asset library path.
In a new Blender instance, make sure the asset path to this file is set correctly, open an asset browser and find the collection assets that are defined in library.blend. They are named asset_1 and asset_2.
Make sure the import method is set to Append (Reuse Data), then drag both of these assets into the scene.
Make sure Instance is turned on in the operator panel options, so that they are added as instanced collections. (Crashes can still happen if this is switched off, but it is a little more consistent with it switched on, I've found)
With both assets added to the scene, immediately undo the actions of appending the assets (Ctrl+Z multiple times).
Blender (very frequently) crashes. If it doesn't, try again.

Note the difference in behavior between appending using this method, and appending using File > Append. The latter seems to work in a more sensible and stable way, with no duplicated rig and no crashes.
