Updating Home Assistant image failed

Running HassOS on a Raspberry Pi 4 (8GB) using the beta build and receiving an error when trying to update Home Assistant Core. ha supervisor logs show the following entries:

21-01-26 18:06:35 ERROR (SyncWorker_6) [supervisor.docker.interface] Can't install homeassistant/raspberrypi4-64-homeassistant:2021.1.5 -> 500 Server Error for http+docker://localhost/v1.40/images/homeassistant/raspberrypi4-64-homeassistant:2021.1.5/json: Internal Server Error ("readlink /mnt/data/docker/overlay2: invalid argument").
21-01-26 18:06:35 WARNING (MainThread) [supervisor.homeassistant.core] Updating Home Assistant image failed

Anyone know how to get past this?

Looks like 2021.2.0b0 is allowing the update, monitoring.
