• Description: My keyboard (Preonic) frequently disconnects and reconnects out of nowhere. Not sure why, might be related to the on-board microcontrolller, but whenever it reconnects it makes sway segfault and crash.

From journalctl -xef I can see that sway fails on xkb_keymap_num_layouts on libxkbcommon library. It seems to be related to the fact that, upon reconnection, the keyboard seems to communicate a number of keycodes higher than the library supports (might be wrong here, I have no clue about how this library or these systems work):

Your stack trace is missing debug symbols. You can get symbols by compiling from source, reproducing the crash and then running coredumpctl gdb and then bt full.

Here are some instructions to compile from source: https://github.com/swaywm/sway/wiki/Development-Setup#compiling-as-a-subproject
