Short description
Crash opening a file with enabled Asset Shelf

Steps to reproduce

  • enable View > Asset Shelf in either the 3D view or the Image Editor
  • save the file
  • revert > crash

Original Report

The program will crash when re-opening a file previously saved in the same version.

Exception:

Unhandled exception thrown: read access violation.
shelf_regiondata was nullptr.

Stack trace:

Exact steps for others to reproduce the error

I've attached the .blend file that causes the crash for me, but I get the feeling it requires a specific asset library configuration. For what it's worth, my asset libraries are quite large.

Easy to repro from scratch:

  • enable View > Asset Shelf in either the 3D view or the Image Editor
  • save the file
  • revert > crash

Most likely fixed by #123385. However I find this a bit too risky for backporting to 4.2, so I'd suggest this workaround for the 4.2 branch:
