There seems to be a null pointer access that can happen. I was able to reproduce this by running the cemu emulator[1] with the new collabora wine wayland driver[2] and opening and closing some sub menus. Adding a trival null check seems to do the trick to stop sway from crashing and returning to tty and everything else works normally.

sway is an i3-compatible Wayland compositor. Read the FAQ. Join the IRC channel (#sway on irc.libera.chat).
Release Signatures
Releases are signed with E88F5E48 and published on GitHub.
Installation
From Packages
Sway is available in many distributions. Try installing the "sway" package for yours.
Compiling from Source
Check out this wiki page if you want to build the HEAD of sway and wlroots for testing or development.
Install dependencies:
- meson *
- wlroots
- wayland
- wayland-protocols *
- pcre
- json-c
- pango
- cairo
- gdk-pixbuf2 (optional: system tray)
- scdoc (optional: man pages) *
- git (optional: version info) *
* Compile-time dep
Run these commands:
meson build/
ninja -C build/
sudo ninja -C build/ install
On systems without logind nor seatd, you need to suid the sway binary:
sudo chmod a+s /usr/local/bin/sway
Sway will drop root permissions shortly after startup.
Configuration
If you already use i3, then copy your i3 config to ~/.config/sway/config and
it'll work out of the box. Otherwise, copy the sample configuration file to
~/.config/sway/config. It is usually located at /etc/sway/config.
Run man 5 sway for information on the configuration.
Running
Run sway from a TTY. Some display managers may work but are not supported by
sway (gdm is known to work fairly well).
