All in the question.
I don’t use it for now and believe it makes my game crash on specific occasions ( landing challenges)
If you downloaded it via Marketplace go to the content manager and there you can uninstall the mod.
If you installed it over the Flybywire Installer launch the installer and click uninstall or update if an update is there.
For the manual installation you have to find the Mod in your Community Folder and delete it
Understood, as simple as I didn’t expect.
