watching SwitchInputMethod results in a crash

[JB0x0003]

Calling fcitx.watchEvent with SwitchInputMethod as an argument causes fcitx5 to crash. Other event types mentioned in the documentation work as expected. I've installed lua5.3-dev with apt because it was throwing errors at not being able to find that version of lua, don't know if that's related or not.

It wrote the following into the console when it crashed.

=========================
Fcitx 5.0.5 -- Get Signal No.: 11
Date: try "date -d @1666957142" if you are using GNU date ***
ProcessID: 1394574

Hope that helps!
