In my environment, when "adb devices" command is executed, "emulator-5554" is displayed as "device" in "List of devices attached".
However, when "Debug" is executed in that state, "filelock_lock: error not already exists" is displayed and the application cannot be executed.
Is this missing adb settings?
Or are there any files that need to be put in the emulator?
please answer.

Have you tried to create emulator in Android Device Manager ?
Does the problem persist when you run the emulator in visual studio ?
