The end goal is to either get the main UI to boot, or to get to 2.3.8.140 or higher which should fix the issue.
So you used the advanced menu to go back to 2.3.7.146 it sounds like? Rolling back to that coupled with a soft reset is the best chance to get the UI to load. DO NOT load a backup if you get to that point.
If you get the main UI to load (even just the screen saying to load a backup) run this endpoint to turn off the z-wave debugging:
@bobbyD is there any other options besides the full reset?
If you end up needing a FULL RESET from the advanced menu in the diag tool, this will also reset both radios so all z-wave and zigbee devices will need to be paired again.
If you had Z-wave devices paired before and you want to restore the hub database backup (for any configured automations and apps), you will need special instructions to avoid pairing conflicts with Z-wave devices.
