Error: Config flow could not be loaded: {"message":"Invalid flow specified"}

I am finally getting around to installing Bluetooth Proxy to an ESP32. I got this far in Settings/Integrations:

discovered

When I click on “CONTINUE”, I get this error:

## Error

Config flow could not be loaded: {"message":"Invalid flow specified"}

It appears that everyone who got this error in the past was installing HACS.

Any tips on how to proceed would be appreciated.

Hi, I get the same error with IMPROV_BT on esp32dev board.

I have no HACS.

I can connect successfully the esp board to the wifi network with IMPROV_BT and later when I’m prompted to add the esp yaml I get this same error.

I am getting the same error … No answer?
