You can find the whole story in Crash on Android 12 Developer Preview 1 about why encountering a black screen when using Scrcpy to stream Android screen in a video stream. Long story in short,

Using rootAVD to root Android devices or emulators, also check the video tutorial from Youtube

git clone https://github.com/newbit1/rootAVD
export PATH=<adb path>:$PATH
export ANDROID_SDK_ROOT=<adb path>
export ANDROID_HOME=<adb path>
# check all available img for running AVDs
./rootAVD.sh ListAllAVDs 
./rootAVD.sh <google_apis_playstore path to ramdisk.img>
# find all devices
adb devices
# test for su
adb -s <device id> shell su
## id
## uname -s

Enter android devices, then

1, install the latest Magisk or update Magisk after executing rootAVD.sh for specific device. You can select the option "Install from external source" or "Direct Install"

2, enable Zygisk from options of Magisk

3, install Zygisk from external storages, like google drive.

4, reboot and open Zygisk from notification center, then install Disable-FLAG_SECURE
