Problem Description

Whenever I start Spyder 5.5.5 on Windows Server 2022 I get it running for about 50 seconds before the window freezes and it's marked as "Not responding".

This happens regardless of:

Install method: it occurs with standalone as well as conda installs
Settings: this happens after spyder --reset as well
Start method: this happens both for a commandline start (with/without debug options), a conda environment start, as well as from the Start Menu.
Interpreter: this happens both for the built-in interpreter as well as an external interpreter

What steps reproduce the problem?

Open Spyder, using either:
- The start menu shortcut
- Commandline from a conda environment: conda activate my-env; spyder
- Commandline from standalone install: C:\Program Files\Spyder > Python\python.exe Spyder.launch.pyw --debug-info verbose

In the ipython console write:

import time
for i in range(0, 600):
    print(i)
    time.sleep(1)

Run the code

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

Expected: the loop finishes in 600 seconds and writes the index each second.
Actual: the Spyder window hangs when the loop is around index 50, i.e. after 50 seconds.

After opening this issue I installed Spyder 5.4.5, that worked without a problem, so that's a viable workaround. However, would like to keep this issue open such that a long term solution can be found.

Hey @b-a0, thanks for reporting. Our new installers for Spyder 6 will come with a more recent Python version and are built with a more modern stack too.

That could help to solve this problem, but let us know if that's case after that version is released in a few weeks.
