Try manually:

adb push scrcpy-server /data/local/tmp/scrcpy-server.jar

What is the result?

What is the output of:

adb shell ls -l /data/local/tmp/

你使用root复制旧版本的server，导致2.0server校验不通过，scrcpy尝试复制新版本server但是adb不能操作用户组为root的文件，你要删掉旧版本并且避免用root权限操作文件

Try manually: adb root

adbd cannot run as root in production builds

root操作文件是大忌
