How to fix flutter devtools opening on the wrong URL?

I changed flutter channel from stable to master then returned to stable, and after this when I try to open devtools from android studio now it opens the URL http://127.0.0.1:9101/... which is a blank white page. I searched for a solution and couln't find any. But when just changed the 9101 to 9100 in the URL, then it worked and devtools opened normally, but now every time I have to do this manually. How can I fix it so that android studio opens it automatically?
