Hello guys

I just bought a Pavo Pico 2 with an O4 used and I can't get it to fly. I set the bindphrase and my Radiomaster Boxer says "Telemetry connected" but I can't arm and there is no input in the Reciever Tab of Betaflight.

And my Boxer works fine with my 5-inch that also has an O4. (On Elrs 3.x and 4.0.1)
Yes I set the right Protocol (CRSF) when flashing and in the Reciever Tab.
Yes my Reciever is wired correctly (It's an AIO board).

Thanks for any help.

Here's what I tried:
- I updated RX and TX to ELRS 4.0.1
- I updated my Boxer to the newest firmware
- I updated TBS on my Boxer
- I flashed the board of the Pavo Pico with the firmware from Betafpv
