I had exactly the same issue. The disk filled up completely and all processes stopped.
It looks to be the logs in /var/log/hostwatch are so large that the disk is full and nothing else will work. The GUI dies.
I had to reboot, connect locally to the OPNsense device, turn off/disable the Interfaces:Neighborhood (see post in German forum) and then manually delete the logs from /var/log/hostwatch.
Once the logs were deleted and I rebooted again, everything appears to be back to normal.
BTW, check out the other posts about hostwatch in the forum. It appears they are all related to this.
