Your sever (in /usr/local/share/scrcpy/scrcpy-server) does not match the client. How did you install scrcpy?

Btw, the latest version is 2.4 currently.

Sorry
Actually I first install 2.3.1 from source code later I installed from Pacman without deleting the 2.3.1 configurations.
Solved by. sudo Pacman -Rns scrcpy && sudo Pacman -S scrcpy.
