The Unity SDK has been working quite well, but for some reason today, all my scenes are broken because “Associated Script could not be loaded”.
I made a new Unity 2019.2 project, loaded in the SDK, and things worked fine for the first hour. Then the same error happened again (maybe after I tried to Build the scene?)
I figured it out. I had the Vimeo Unity SDK installed, and when exporting a Build, things broke. Fixed by uninstalling Vimeo from my Unity project
