Google Play Protect issue on Rock 4 SE

I am new to Rock SBC, and just get my first Rock device - Pi 4 SE, after unboxed, flash an image - rock4b-se-android11-20220819-1907-gpt to a 16GB SDCard, the SBC can boot into this Android system but prompt out a error message: This device isn’t play protect certified while trying to setup a Google account, then many google services arenot able to play, any one can help?

Many Thanks.
