TypeError: initializer for ctype 'struct cpVect' must be a list or tuple or dict or struct-cdata, not numpy.ndarray

I just updated from ev3sim 1.3.3 to 1.6.5 and it isn't working anymore. The same problem occurs if I try to run it using the batched commands system.

(2020-Simulator-Team-P) C:\Users\sachi\PycharmProjects\2020-Simulator-Team-P>ev3sim bot.yaml bot.yaml
Simulating with seed 3103703429

=====================================================
DEPRECATED: Running ev3sim without the batch argument will be removed in a newer version of ev3sim.

To find out how to use batch commands, consult https://ev3sim.mhscsr.club/batched_commands.html

The same error occurs if I try to run with a batched flag.

Downgraded to 1.3.3, downgraded numpy to 1.19.0 and pygame to 1.9.6, used the demo controllable.yaml file packaged with ev3sim and still having the same problem. I suspect it's due to a conflict with another package or perhaps a problem with my environment.

Problem still occurs in a fresh venv instead of a conda env. I believe I've tried every sensible version combination of numpy, pygame and ev3sim now.

Thanks for testing all of those configurations, and apologies for taking a bit to answer. This seems to be a problem with pymunk==6.0.0. I'll probably try fix this as part of #184 , but for now you can fix it by running pip install pymunk==5.7.0.

Thank you so much, this was driving me absolutely crazy.
