• Description:
  From within a different compositor (in this example cosmic) do the following steps:

git clone https://github.com/swaywm/sway
cd sway
meson setup build
ninja -C build
./build/sway/sway

sway will crash, it seems to be due to a recently added assertion in wlroots.

[emersion]

Sway crashes on shutdown due to the new asserts in wlroots, that's a known bug: #8509

The real error is:

00:00:00.059 [ERROR] [sway/config.c:454] Cannot find config file

Closing as a duplicate.
