WiFi adapter on RTL8812bu chip don't work in the monitor mode

I bought Dual Band USB Adapter AC1200M based on chip RTL8812bu.
Its details:

idVendor=0bda, idProduct=b812
Product: USB3.0 802.11ac 1200M Adapter
Manufacturer: Realtek
SerialNumber: 123456
ID 0bda:b812 Realtek Semiconductor Corp.

I was trying to install all drivers which I was able to seek:
https://github.com/MeissnerEffect/rtl8822bu
https://github.com/cilynx/rtl88x2BU_WiF … 4.20170613
https://github.com/cilynx/rtl88x2BU_WiF … 71012-5044
...and a few other.
But when I want to turn on monitor mode I get this error

# systemctl stop wpa_supplicant
# systemctl stop NetworkManager
# ifconfig wlp0s26u1u1 down
# iwconfig wlp0s26u1u1 mode monitor
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlp0s26u1u1 ; Operation not permitted

airmon-ng doesn't works with this driver, saying operation not permitted when trying to enable monitor mode in this card.
Using iw command I was able to turn on monitor mode but airodump-ng sees nothing. But I'm sure there should be a lot of networks.
Almost all my attempts to work in the monitor mode go to system freezes anyway.
What kind of logs and settings I should you show to get your advices?

According to https://github.com/MeissnerEffect/rtl88 … kefile#L69 this is disabled by default, adjust that line and rebuild the driver and retry.
