Worked: Unsure

Short description of error:
Dragging a asset from the asset browser while the thumbnail is still loading results in a crash. Here's the crash log:
Asset browser thumbnail crash.txt
2021-07-30 15-52-30.mp4

Exact steps for others to reproduce the error:

Create a asset library with a "large" number of assets. By "large", I mean you have enough assets to make the loading of all the assets + thumbnails a longish process. For example I have a asset library with 60 cloud objects, or 60 materials. I will provide a .zip containing a collection of .blend files you can add to your asset library for use in triaging this bug. Custom thumbnails seems to make the thumbnail loading process slower and so the bug is easier to reproduce with custom thumbnails.
Open a new .blend file.
Open the asset browser and open your library with the assets.
As the assets thumbnails are loading, click on drag on one of the assets as if you were going to add it to your viewport. Blender should crash.
