Thanks for your prompt response. I'm pretty sure that this is related to https://bugs.launchpad.net/snap-store-desktop/+bug/1867417 which is showing as fixed but subsequent comments suggest that an issue exists for anyone that might not be using themes that are not included in the gtk-common-themes snap.
