When active, crashes github actions testing via GUT

[db0]

Very weird issue, but I thought I'd report it anyway.

I am testing my game after every push using the GUT plugin and github actions. However if I have this plugin active, it will cause Godot's parser to fail and the tests will time out due to Godot being effectively crashed.

Example: https://github.com/db0/hypnagonia/runs/6219215833?check_suite_focus=true#step:4:26

However if plugin is disabled, everything works as expected.

Frustratingly, everything seems to work fine both in my local PC, and in a lightweight linux VM I deployed trying to simulate github action runners. It only fails in this way in github actions.

My project is free software, so feel free to investigate using it if you wish.
