swappy fails to start "Failed to register: Timeout was reached"

[k-jell]

I am using swappy 1.5.1-1 on Arch and it is not starting anymore. When trying to run swappy -f screenshot.png for example, this error appears:
Failed to register: Timeout was reached. journalctl and dmesgdon't show anything related.

Other versions that might be relevant:
sway 1:1.8.1-5
wayland 1.22.0-1

Edit
Isse has been gone. System has been updated a couple of time since then, not sure which update fixed it.

I'm running into this after upgrading to Fedora 41. If I find anything I will update.

user@host:~$ grim -g "$(slurp)" - | swappy -f -
Failed to register: Timeout was reached

Edit
And it's fine after a reboot... Couldn't reproduce.
