(Duplicate of android device monitor not coming up)

Ensure that no other instance of monitor app is running. It may happen if Android Studio crashes or otherwise.

Kill the monitor process and restart.

I had the same issue, which was fixed just by rebooting my laptop! You can try to do so!

I use a Mac and have encountered this problem.

Finally, I found out that I have opened the Android Device Monitor, so I closed the previous one and reopened it and it started successfully.
