Describe the bug
I have a Python 3.9.5 virtual environment running MuJoCo (3.1.2) in my setup on Ubuntu 20.04 with a UR5e from mujoco_mangerie where I am trying to manipulate a soft body using a Hand-E gripper. Each UR5e actuator is being controlled using the new PID controllers introduced in version 3.1.0 (December 12, 2023). When running this simulation I would like to save and load different states of my simulation, I can understand on the documentation that keyframes are one of the ways to solve this. I like this approach as it enables me to read and changes parameters in the keyframes xml.
The problem appears to be a clash between the new PID controller plugin and loading in keyframes, as when both are included I simply get a Segmentation fault (core dumped).
I have attempted to isolate the problem with just the UR5e manipulator in the scene (along with axes and lights), but the problem seems to persist.
To Reproduce
While reproducing the error might take a little setting up wrt. the meshes of the manipulator, I have here included my scene xml as generated form Save xml
Save xml button result
```
```
Expected behavior
The expected behavior would ideally being able to run my simulation with both keyframes and the PID controllers. If there are alternative solutions or I am somehow misusing the tools within MuJoCo please let me know.
Error Messages
As mentioned previously the error message when loading in the scene as shown below
mj.MjModel.from_xml_path(filename=self._scene_path)
Is simply a
Segmentation fault (core dumped)Desktop (please complete the following information):
OS: Ubuntu 20.04
Python Version 3.9.5
Mujoco Version 3.1.2
Python virtual environment
Any and all help, information, solutions to this or an alternative solution is very much appreciated, thanks in advance.
