Unable to install packages on 3.8.17-slim

Trying to install any package, for instance pandas, on 3.8.17-slim (that at the moment is the tag corresponding to 3.8-slim) image causes the following error:

Launching in the Python session the following code

from threading import Thread

def threaded_print(arg):
    print(arg)

thread = Thread(target=threaded_print, args=("Hello World",))
thread.start()

raises

RuntimeError: can't start new thread

When downgrading to tag 3.8.16-slim the packages installation and the code snippet work just fine.

This sounds similar to #835, and #837, so the answer is very likely: #837 (comment) (TLDR: update Docker, libseccomp, and runc, or use the -bullseye images)

Thanks for your quick answer! The host machine is Windows and updating Docker solved the issue.
