I think It's also wired after that PR the 8852BE driver is still not added into the OS build.
Now I have compile the the DKMS driver by myself, you can simply install it through APT.
Download here
sudo apt install -f ./rtw8852be-dkms_1.0.0_all.deb
Rember to turn off system auto-suspend:
sudo systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
Good luck!
