Hanging `python.exe` threads when running any az cli commands

### Describe the bug

In a Microsoft Terminal Powershell, I run any azure cli command, this completes successfully.
However, the `python.exe` process which ran when the command was issued remains, using up a full single core.
This continues with each additional execution of the az cli, with the number of `python.exe` equal to the number az cli calls made.

For example, calling `az --version` 3 times, results in 3 `python.exe` processes remaining, with full single core cpu demands.
Each call completes successfully


Even after closing the terminal session, the processes remain:


The processes can be killed through Task Manager, but will remain taking up significant system resource if not killed.

### Related command

Tested with any call to the azure cli `az` tools.

### Errors

There are no error messages, just hanging processes.

### Issue script & Debug output

There is no bug or error report.

### Expected behavior

The expected behaviour would be the `python.exe` threads terminating on the successful completion of the `az cli` command.
