I followed the "making an app" section on the page https://www.espruino.com/Bangle.js+Clock
and was able to set the app as my primary clock, and try it out for a day or two. I wanted to make a couple last minute tweaks and wanted to replace the app, but writing over the file didn't show my changes. So I tried, using the IDE, to remove the files associated with my app, and now my bangleJS2 only shows a black screen, no matter what I do.
I went to the app loader, and saw my app listed as "unknown app bradbury (unknown version)" and when I clicked the trash icon, I was given the alert "Unknown app bradbury removal failed, TypeError: Cannot read properties of undefined (reading 'split')" and my watch says "Erasing bradbury..." but stays there, and does nothing beyond that. I tried long-press rebooting, but only returned to a black screen. I repeated the process to the same results.
I'm not sure what to do, and I'm fine with factory resetting if necessary, but not sure how to do that since I only see a black screen.
