@stephenb can you check [the FB line](https://github.com/elastic/beats/blob/main/libbeat/cmd/instance/beat.go)? Maybe the config param `allow_older_versions: true` is missing in filebeat.yml?

Also, there is a [topic](https://discuss.elastic.co/t/cannot-start-filebeat-because-of-instance-beat-go-error/261472) where a module wrong param cause issue. However all modules are disabled in yash case.
