Each time comes back and I need to restart my pc to debug typescript.

Also tried

taskkill /im chrome.exe /f
adb kill-server 
adb start-server
adb devices

None of that worked also.

Any ideas?

The solution worked for me is:

Open task manager, find NodeJS server process and kill all.

You can run Ionic server in another port by using a command like:

ionic serve --port 8101
