The notebook (as posted at https://github.com/sagemanifolds/SageManifolds/blob/master/Notebooks/SM_black_hole_rendering.ipynb) works well for me with SageMath 10.1 on Ubuntu 22.04.
It seems that you are facing some parallelization issue. Have you tried to run the cell 29 instead of 28 as suggested in the notebook?

Update (15 Nov. 2023):
The error might be due to the memory limit of your CoCalc account. I've tried the same notebook (with parallelization) on my CoCalc account with 4 GB memory and with SageMath 10.0 kernel (due to the issue https://ask.sagemath.org/question/74323) and the notebook runs nicely. If you cannot increase the memory on your CoCalc account, consider lowering the resolution by selecting the following cell at the beginning of the notebook:
n_cpu = 4
n_geod = 100
nx, ny = 180, 90
