1) I've tried disabling my plug-ins. I'm currently just using Ad Blocker and a few Google Docs plugins. No change.
2) The current project is Audio Source, Control Lines and 3 audio sources. The current project is around 30 seconds long.
3) The error pops up right away. Typically, it doesn't show the circle progress bar at all.
I am a teacher and my students are using this program as well. We are all on MacBooks. The student laptops are all the same and they do not have any permissions to add extensions/plugins. Some of the students are having the same issue as myself while many others are not. It was not until the recent update that these issues started occurring.
The good news is I am not having the same issues when using Firefox. My students, however, are forced to use Chrome or Safari.
