Missing seccomp profile on arch

Tried to install a snap (pulsemixer) on an Arch (antergos) VM and it seems to fail to launch due to missing seccomp profiles. Am I doing something wrong?

[alan@antergos-amd64 ~]$ sudo snap install pulsemixer
pulsemixer 1.3.0 from 'snapcrafters' installed
[alan@antergos-amd64 ~]$ pulsemixer 
Can not open /var/lib/snapd/seccomp/profiles//snap.pulsemixer.pulsemixer (No such file or directory)
aborting: No such file or directory
[alan@antergos-amd64 ~]$ snap version
snap    2.27.3-1
snapd   2.27.3-1
