free() invalid pointer at startup (workaround available)

[jveijck]

OS: Ubuntu 20.04
Running Groot after download from git (2022-07-29).
After fixing build issues for non ROS2 system (ament fails and later the submodule BehaviorTreeV3 was not found correct).
then I was enable to build Groot.

I starts and I can select "Editor | Monitor | Replay". If I select "editor", groot crashes with the message: "free() invalid pointer at startup".
If a run it with "valgrind ./Groot" it starts up correctly(slow, but it starts). Valgrind reported several errrors:
