Additional Information

I wanted to add that this error occurs during HA reboot. BT still seems to work fine though.

I have the same issue and I think my next step is to remove all of my BT config from the UI and filesystem and try to reinstall and reconfigure it. Will report back!

Edit: I also wonder why so few of us are affected. What's the commonality between our configs?

[sleveille4]

i too have the same Detected "blocking call to import_module" in my logs.

maybe as nothing is wonrg in use not many do check the logs?

this causes my BT instances to show as Unavailable

I did the full reinstall of BT but the issue remains.
