Watch stucks on "Loading..." after long waiting

### Affected hardware version

Bangle 2

### Your firmware version

2v19

### The bug

Previously I installed several new apps. I thought that any of new app is the reason of the issue. I suspected `cassioWatch` , but after the rallback to the the previous clock app - the problem still reproduces permanently.

After several hours of waiting display stucks with "Loading..." message, with no further actions. Also I noticed that the battery is becoming low much faster.

While rebooting the watch, I also noticed `BUFFER_FULL` message:

After reboot I still get the same behavior.

There's still a free memory on the device:

For now I don't understan if it's app related issue. And if it's app related issue, how can I find out what app affects this behavior (maybe there are tools for that?)?
Is there a workaround for this issue?

### Installed apps

dragboard (0.08), android (0.31), messages (0.60), messagegui (0.73), widbat (0.11), alarm (0.42), boot (0.59), notify (0.13), health (0.27), setting (0.63), about (0.14), sched (0.22), widalarm (0.01), widbt (0.09), widlock (0.08), widid (0.03), messageicons (0.05), widmessages (0.05), showimg (0.02), fileman (0.03), dtlaunch (0.24), weather (0.25), owmweather (0.03), dvdbounce (0.01), compass (0.09), espruinoterm (0.01), waypoints (0.01), speedalt (0.13), gbmusic (0.12), antonclk (0.11)

Start by reproducing the issue on a Bangle 2 running firmware 2v19, paying attention to the prolonged wait, battery drain, and BUFFER_FULL message. Isolate the installed apps to determine whether one causes the failure; done means identifying the trigger or establishing a reproducible device-level cause and documenting a workaround.
