Updated OpenThread Border Router 2.12.0 No Longer Starting

OpenThread Border Router 2.12.0 no longer starting after upgrading from 2.11.1. HAOS core 2024_11.2 on Qnap NAS in VM. Smlight SLZB-06p7 LAN adapter. Rebooted adapter, restarted HA, uninstalled and re-installed the add-on and the integrations. Add-on starts for a few seconds and turns itself off. Reverting to OTBR 2.11.1 brings everything back to normal. Does anyone else encounter the same issue particularly with this adapter?

Maybe take a look at the OTBR logs to see what happened.
Here is a cut-n-paste from the changelogs, so maybe something related to adapter firmware:

2.12.0

  • Bump universal-silabs-flasher to 0.0.23
  • Bump OTBR firmwares to latest versions
  • Bump to OTBR POSIX version b041fa52daa (2024-11-14 08:18:28 -0800)
  • Add radio firmware version to discovery information

Waiting to hear what the adapter’s manufacturer has to say.
