Access point not working when in monitor mode

[KyoSenshi]

I'm using a Raspberry Pi 4 Model B Rev 1.1 with Raspbian as it's recommended in the documentation and the Kernel version is 4.19.75-v7l+.

As i have followed the documentation step by step and installed nexmon the monitor mode is working only when wlan0 interface is down . In the last section of the documentation it says that : It is possible to connect to an access point or run your own access point in parallel to the monitor mode interface on the wlan0 interface.

I have created an ap mode on wlan0 interface and it's working.

So when im using iw phy iw dev wlan0 info | gawk '/wiphy/ {printf "phy" $2}' interface add mon0 type monitor and then ifconfig mon0 up the driver crashes to restart it im using modprobe -r brcmfmac && modprobe brcmfmac.After that i have to create again the mon0 interface and the wlan0 is not working

So the problem is this, when the two interfaces (wlan0 for Access point mode and mon0 for monitor mode) are up the driver crashes.Can the two interfaces work in parallel?

Is there a way i can solve this?

Raspberry Pi 4 Model B Rev 1.1 running kali-linux-2019-4-rpi3-nexmon-64-img-xz Linux 4.19.81-Re4son-v8l+ brcmfmac (Broadcom 2711)

I have a similar issue; using the official kali linux image for RPi 4; SSHing into it over a mobile hotspot; after creating & bringing mon0 up, i lose the SSH connection; have to restart Pi to restore CLI access, and the mon0 interface is gone; it's like we can't access the wireless AP when it's in monitor mode; both interfaces not working in parallel.

is there a way to solve this that i dont know of?
