Again: Resource temporarily unavailable

Problem Description

I’m starting Spyder in a virtual anaconda-environment called “main”, I’m doing this via the shortcut provided by Anaconda in the start menu. When Executing an entire script by pressing F5 and afterwards entering reset to reset the console I’m getting a Again: Resource temporarily unavailable-error.

I’m getting the same error when using getpass.getpass() in a file and executing it via F5.

None of this happens when I execute the same code by marking the lines and pressing F9. If I only execute code via F9 I can use reset fine, it becomes only unusable after pressing F5.

What steps reproduce the problem?

1. Start Spyder in an environment using the shortcut provided by Anaconda. 2a. Execute some file by pressing F5, then enter reset. 2b. Use getpass.getpass() in the file you’re executing.

What is the expected output? What do you see instead?

No error.

In the end I scrapped my entire bugged Anaconda installation and did a clean reinstall using Miniconda.

The problem is gone now.

I have no idea, sorry.
