I tried version 6.2.0, 6.1.3, 6.0.8, and 5.2.4. All versions >= 6 do not work:

Running Fantomas manually works as expected on all versions.

Hey @Wouter8, what Rider version are you using? 2023.2.1 works just fine for me with the latest Fantomas.

I just updated. Turns out I'm running 2022.3.3 😨

Let me install 2023 and let you know if that indeed was the issue

2023 is working just fine. Sorry for wasting your time...
