I don't know, i learn the software for the moment, because Twitch studio is to limited for me (and ending support on mac)Have you or some tool you are running modified the files (accidentally)?
I don't think i have modify something, just install some plugin. OBS launch when i remove the Scene Switcher plugin.
The terminal command work perfectly. Thanks !
When you say "if you don't need the Twitch functionality" it's not possible to stream on Twitch after ? Because yes that's the goal ^^
