ERROR (Thread-13 (_connect)) [root] Uncaught thread exception

[PWhite-Eng]

Describe the bug
After an update to HA (sorry I do not know which one), Ramses RF failed to set up. It has been working fine previously

see logs below for error details (time 2025-01-26 12:27:58.040)

Additional context
Stand alone Home Assistant running on a raspberry Pi 4, with an evofw3 usb device installed (I have checked this and it is outputting the correct messages, as can be seen by packet.log)
