Hello! Apologies for the slow reply, I was away from development for a couple months because I got married but hopping back into it now!

Based on the error message this seems to be an issue with the version of Java that the launcher is using for Minecraft. MIMI depends on the built-in Java MIDI system (com.sun.media.sound) to function properly and it seems that for some reason the particular version of Java that the launcher is using doesn't include a compatible version of the MIDI system.

Since you mentioned that it is able to start with the other launcher it sounds like this is an issue with the version of Java that the launcher you're trying to use is providing and you may need to open an issue with them.

This issue has been automatically marked as stale because it has not had recent activity. It will be closed if no further activity occurs. Thank you for your contributions.
