Locks up attempting to edit .mid channels exported from MuseScore

Explanation: For context, I'm in the middle of a project rewriting a marching band piece to run it through Midis2Jam2. When I export the .mid through MuseScore, the instruments are all sorts of mismatched, so I run it through signal so I can reassign and adjust the channels as needed. However, after my latest update to the project, I can't change anything in the file with signal. When I click on one instrument, it freezes with a greyish (my chrome profile is grey so I'm guessing it's just that) screen for a second or two, then allows me to edit the channel, but then when I go to the next instrument, it fully locks up with a solid white screen, and I'm forced to reload the page and start over, which then the same thing will happen.

To Reproduce:

1. Grab the mid here
2. Open it
3. Double click on a channel to edit it's instrument.
4. If it doesn't lock up yet, open another channel and try to edit it's instrument.
5. If it doesn't lock up by the second or third change then it might just be my dogshit MacBook
