Last source coded compiled in Windows.

Attached the file with error, just open it.

This problem was reported as part of #77003, but after checking I have seen is related to rigid bodies initialization.

The crash is because rbwvariable is NULL in DepsgraphRelationBuilder::build_rigidbody function.

This is callstack of the crash:

I cannot reproduce this with either the latest stable or current development versions of Blender.
The file opened without problems here.

Does any step is missing in the description?
Did this file has worked in other blender versions?

It's strange...today I can open the file...maybe it was because I saved with new version. Ok, we can close it and if we get the error again we can reopen or create a new report.
