The same issue with 2025 version. Terminals switching doesn't work anymore. So the bug became constant without any possibility to avoid.

Either you clolse terminal through "x" button inside IDE or close IDE completely. The process is still running.

It was the same a few years ago as I remember and nothing was fixed. Don't know why. It's frustrating since you have to go to the task manager and find that node process which is still running and kill it manually. Otherwise you'll receive an error that port is already in use when you try to run another application if you have many nodejs projects which use the same port.
