Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-07-21 18:41, hash: `rB64bb49fa4e3c`
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.
