Thank you hobanagerik, I am re-installing the whole Oculus app to see if that fixes it, I will try to play a bit without VR as you suggest just to rule out problems regarding the simulator installation.
If it doesn’t work with a new Oculus installation I am lost, and the next step is to reinstall the whole Windows, which I don’t want at all.
Also the error is weird, I googled it and didn’t find anything
