Crash on windows when combining "--minimize", `animatedGeometry`, and `muscles`

[brettle]

Describe the Bug On Windows with the current master branch (34dfe53), when running webots with --minimize, if I run a world with a Track containing animatedGeometry, and then try to load a world with a muscles node, webots crashes.

Steps to Reproduce

1. Run:

   ./tests/test_suite.py --group api tests/api/worlds/robot_urdf.wbt  tests/api/worlds/supervisor_set_hinge_position_dynamic.wbt`

   or

   ./tests/test_suite.py --group api tests/api/worlds/robot_track.wbt  tests/api/worlds/supervisor_set_hinge_position_dynamic.wbt`

   The first test will pass but webots will crash when running the second test.

The crash does not occur if I comment out the --minimize option is test_suite.py, remove the animatedGeometry node from robot_track.wbt/robot_urdf.wbt, remove the muscles node from supervisor_set_hinge_position_dynamic.wbt, or when running CI which uses a sofware renderer.

Expected behavior Should not crash.

System

System              : Windows 10 Version 22H2 64-bit
Processor           : Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz
Number of cores     : 6
OpenAL device       : OpenAL Soft
OpenGL vendor       : NVIDIA Corporation (0x10de)
OpenGL renderer     : Quadro T1000/PCIe/SSE2 (0x1fb9)
OpenGL version      : 4.6.0 NVIDIA 538.78

Additional Context

My best guess is that perhaps a bug in the code which destroys some animated geometry objects is causing memory corruption that is tickling the muscles code.
