nrf5340 - DFU WiFi - Facing BLE "Endpoint binding failed with -11" error

Hi,
I checked DFU over Wi-Fi in a separate project (net/download) that only included DFU and Wi-Fi-related functionality. In which FOTA is working as expected.

In our custom board (nrf5340-nrf7002) and our application project includes BT-GATT, Wi-Fi, a timer counter for scheduled work, GPIO for hardware interrupts, I2C for an OLED display, and ADC functionality.

I’m now working on integrating BT - GATT to DFU working project. However, I’m encountering a BLE  issue. "<err> bt_hci_driver: Endpoint binding failed with -11"

Could you please assist with resolving this?

Here I share my project.
