Insync-headless not syncing

insync-headless is running but not syncing - I’m running arch linux with the latest aur version of insync (that’s the package manager). For some reason, insync itself won’t run as fontconfig has changed.
The outfile isn’t showing any useful output:

Exception happened during processing of request from

Any advice on what I can do?
