Device can't join in OTAA when the program util_pkt_logger is running

[Sertixzk21]

Once the program is off, my device automatically join, as if the program was occupying all my gateway traffic, even tho I can capture datas payloads without problem.

you cannot join with util_pkt_logger, it is just a tool to log incoming packet, not related to LoRaWAN.
And you cannot run util_pkt_logger in parallel of the lora_pkt_fwd utility as both would use the same HW, which is not supported.

I see, do you think there's a way to capture and send payload at the same time?
