Temporary solution - downgrade gcc and gcc-libs to version 12.2.1, then you can build package successfully.

GCC13 moved a few includes around so some things (like stdexcept and string) that used to be implicit aren't anymore.

I'm on Arch and lazily sed'd it inline in the PKGBUILD, and I don't feel like screwing around with git on the spare machine I'm playing with hyprland on, but the fix is literally

sed -i '10 i #include <stdexcept>\n#include <string>' include/modules/sway/ipc/client.hpp

[D3vil0p3r]

I think only <stdexcept> needs to be included. I see already <string> on the client.hpp file.
