For the opencap-processing repo, we instruct people to pin OpenSim to a previous 4.5 version with this command:
conda install -c opensim-org opensim=4.5=py311np123
It looks like some users may run into issues if they use more recent versions of OpenSim with the time index being out of range in a TimeSeriesTable.
