System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce RTX 2070 SUPER/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: version: 2.93.0, branch: master, commit date: 2021-06-02 11:21, hash: 84da05a8b8
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-07-21 18:41, hash: 64bb49fa4e
Worked: (newest version of Blender that worked as expected)

Short description of error
blender is unable to bake fluid simulations via api.

Exact steps for others to reproduce the error

I have uploaded a script which produces this error. If you run this script (baking should take about 20 seconds) and then try to play the animation you will see the 'SystemError: PyEval_EvalCodeEx: NULL globals' error. If you attempt to run it again blender, after attempting to view the animation, blender will crash.

I want to confirm that this is NOT a problem with file naming.

The behavior is identical for both 2.93 and the latest 3.0 release.

There is an original submission here: https://developer.blender.org/T90031

Thanks again!
Nathan

Thanks for the report. Marking this as known issue since it depends on the old particle settings which is end of life .
