Device Connection Failed,

When I try to connect to my banglejs 2, I get this error in the App loader. Here's the console log:

Sometimes, the logs only get to the puck.js:406 BLE Connected part, and the "Getting app list" at the bottom hangs at 0%. I do not know how this is triggered, and I haven't figured out how to affect it.
INFO
The watch is on the newest version (as of now), 2v13.
I also cannot use any other device to upload code (or apps) to the bangle js.
However, I can use nRF Connect to flash new firmware.
When I received the watch two days ago, I was able to upload code to it, and I haven't been able to since today. I don't remember installing any apps that might affect this, except the iOS integration app, which I've deleted with no effect. I have tried different instances of chromium, and a separate live linux system (mint) with no change.
Thanks in advance!
