OPTR crash / RCP failure detected /SMLIGHT Ultima 3

Hi everyone,
I’m trying to integrate matter in my HAOS.
Using SMLIGHT ultima 3 with CC2674P10 chip (firmware 20240727)
After multiple fail i successfully added 2 devices by miracle by my OTBR stop working after a minute in loop.
Here is an extract from logs:

Here is my simple config.


If someone get an idea i would be gratefull. I already try to flash CC2674P10 firmware to the dev version (20250325) without success.

Solved when i use OBTR official add-ons instead of community OBTR network add-on :frowning:
