Sorry for the lack of responses until now Richard.
The problem is not likely a broken update of the chromium snap, but rather the update mechanism itself that messes with font caches, so reverting to a previous version, while possible (see https://snapcraft.io/docs/getting-started#heading--revert), wouldn't fix the problem for you I think.
I'm wondering whether this is happening when the chromium snap is being refreshed while it is running, or if it also happens when the snap is updated while it is not running?
If the former, you might want to enable Refresh App Awareness (https://forum.snapcraft.io/t/wip-refresh-app-awareness/10736), it should help mitigate the problem by preventing updates while chromium is running.
