5.4 xHigh

Microsoft Windows NT 10.0.26200.0 x64

What terminal emulator and version are you using (if applicable)?

PSH 7.6.0

What issue are you seeing?

This is just one example. Doing /stop doesn't change the number. The number of terminals in my task manager is close to 13-15, and it keeps building up. Maybe there are some leaked/zombie threads that I dont see that never close.

What steps can reproduce the bug?

I don't know honestly, I just work normally, things that sometimes require external powershell terminals to be launched by Codex for python.

This has been going on for a while, I think since at least version 110.

What is the expected behavior?
