Metro / ADB not connecting

When I start my android simulator on my windows 10 PC using expo ( 9th lesson in “The Ultimate React Native Series: Fundamentals”), sometimes, I can’t open the developer tools (control + m), and sometimes I get the error that I can’t connect to metro:

“Error opening simulator. Check Metro logs for details” in the bottom right of the http://localhost:19002/ page.

Sometimes I get this err:
“Expo Developer Tools is disconnected from Expo CLI. Use the expo start command to start the CLI again” on the top the http://localhost:19002/ page.

I tried about 5 times to delete and to install new virtual device, and every time i get one these two errors.

And when I try to run chrome debug, I get this error:

Please advice, Thanks!
