Almost all files suddenly got deleted, file in storage.list() but doesn't exist when I try to read it

I believe my watch is running bootloader 2v12 and firmware 2v14.

Earlier today, my watch froze in the messages app and wouldn't respond to me trying to close it with the touch screen. I held down the button for a few seconds, and a loading box appeared. This loading box was the wrong color (black text on a white background even though I use my watch with a dark theme), and never disappeared. I eventually did a full reboot of the watch, and it stays on the light-themed Banglejs logo forever. If I run load() through the console, the loading box appears and never disappears. I noticed that manually trying to load() a file failed, so I called storage.list(). It appears that almost all of the files were deleted from my watch, with only the following remaining:

• widlock.wid.js
  
• widlock.info
  
• wid_a_battery_widget.wid.js
  
• wid_a_battery_widget.info
  
• calendar.img
  
• `ea,p $ (\"
  
• !AP
  
  

The Javascript and info files appear to be unharmed, calendar.img and `ea,p $ (" appear to be binary files. I'm not sure what is supposed to be in calendar.img, but I feel like `ea,p $ (" probably isn't supposed to be there because the name looks like a random chunk of minified code code. Interestingly, when I try to read !AP, I get undefined, even though the documentation says that this only happens when the file does not exist, and the file does show up in storage.list(). Am I misunderstanding something, or does this sound like a bug? Normally I'd just blame my own code for this and move on, but I've been running the same code on the watch for almost a month straight and a file showing up in storage.list() but not existing when I try to read it sounds like filesystem corruption to me.

I am aware that all I should need to do to fix this is go to the app loader and reload my apps. However, before I do that I want to recreate the filesystem just in case it's corrupted. Is there any way to do that? And before I do any of that, is there any information I might be able to dig from this that would be helpful?
