Adb backup does not work on my HarmonyOS 2.0 phone

Question

When I tried to back up my app data, it doesn't work. Specs are listed below:

Huawei mate 10
HarmonyOS 2.0.0
version: 2.0.0.230

I just run

adb backup -f phi.ab -noapk -noshared -nosystem com.PigeonGames.Phigros

when the app that I want to backup is open. But my phone doesn't even display the "full backup" interface.

My computer shows:

C:\Users\BingHeng\Desktop>adb backup -f phi.ab -noapk -noshared -nosystem com.PigeonGames.Phigros
WARNING: adb backup is deprecated and may be removed in a future release
Now unlock your device and confirm the backup operation...

Then nothing. It just creat a backup file with 0 byte.

I am sure that my mobile phone has been connected to the computer, and all other ADB commands can be used normally. Like "adb install", it can be used.

I don't know what I should do now.

Have you unlocked your phone and checked if an interface shows up? Have you tried closing and stopping the app from running in the background before initiating the backup? — JumperBot_, Aug 03 '22 at 02:05
I am sure that I have unlocked my phone and opened the app that I want to backup. — OrderChaos, Aug 06 '22 at 03:03

OK, I have found the problem. Just delete the app named "冰箱" I had installed before.
