The radio firmware on your Home Assistant Connect ZBT-1 could not be determined

The problem

After an update a few months ago my ZBT-1 Connect stopped working. Trying to reflash the firmware I get the following error in System->Hardware->Configure.

I assumed I had a bad ZBT-1 and got a replacement, but the brand new one has the same issue.

I have deleted/disabled Thread/Open Thread Router/ZHA thinking the integrations were using it but nothing changed.

What version of Home Assistant Core has the issue?

core-2025.1.2

What was the last working version of Home Assistant Core?

Unknown

What type of installation are you running?

Home Assistant OS

Integration causing the issue

Thread and Open Thread Border Router

Anything in the logs that might be useful for us?

Stopped working after an HA update. One or two versions ago. 

I did run out of diskspace at one point making some updates have trouble. I since resolved that.

Additional information

Ideal setup. Home assistant yellow's built in radio controls my Zigbee switches. (This also had trouble and broke but I think I got it working again)

ZBT-1 will be controlling my thread devices
