System Information
Operating system: Windows-10-10.0.19043-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 2060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 471.41

Blender Version
Broken: version: 3.1.1, branch: master, commit date: 2022-03-29 17:50, hash: d91843f3b6
Worked: (newest version of Blender that worked as expected)

Short description of error
If same object is dragged from asset browser as link and append (reuse data), and then dragged one more time (reuse data),
Blender crashes.
I upload a GIF animation below.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]

Prepare some object and mark it as asset, and save .blend for Asset usage.
Prepare new project and prepare asset file path settings.
Drag object from asset browser, as link.
Drag same object from asset browser, as append (reuse data)
(* the position of first object behaves strangely here. as shown in above GIF animation. This can be another bug.)
(* There are two objects with the same name in the scene at this stage, linked and not linked.)
And then drag the same object again as append (reuse data)
Blender crashes.

tries to get the boundingbox of the linked object, but that has no data:

It is not a regression, but since it is a crash in a recent feature and not an operation one would only very ralrely run into, will dare setting this to High priority.
