The error message "adb.exe: failed to check server version: protocol fault (status 00 1b ffffffd0 02?!)" usually occurs when there is a communication issue between the Android Debug Bridge (ADB) and the Android device/emulator. This error can occur due to several reasons, including:

  1. ADB server is not running: Ensure that the ADB server is running on your machine. You can start the ADB server by running the command adb start-server in a command prompt.

  2. Incorrect ADB version: Make sure that you are using the correct version of ADB that is compatible with your Android device/emulator. You can check the ADB version by running the command adb version in a command prompt.

  3. Connection issue: Check if the device/emulator is connected properly to your machine and that USB debugging is enabled on the device/emulator. You can also try reconnecting the device/emulator and restarting the ADB server.

  4. ADB configuration issue: Check if there is any issue with the ADB configuration file (adb_usb.ini) located in the .android folder in your home directory. You can try removing the adb_usb.ini file and restarting the ADB server.

  5. Firewall or antivirus issue: Sometimes, firewalls or antivirus programs can interfere with the ADB communication. Try disabling your firewall or antivirus temporarily and check if the error persists.
