I have a Windows 10 PC which has recently developed the following interesting problem. I write a lot of Python code and long-running scripts have recently started quitting for, as far as I can tell, no reason.
As an example, I can start my Django-based webpage with
python manage.py runserver and it will occasionally load in the browser, but as soon as I try to do anything with it, the script will stop without any kind of exit code or error message. This same script was running fine until recently and I do not know what might have changed.
It might be related to the number of programs I have running - they tend to die more quickly when multiple windows are open - but as the CPU usage and memory are consistently under 50% utilised, I can't imagine why this would be a problem.
I've tried running my code in debug mode, but as the code struggles to start and as this affects multiple scripts using multiple packages, often with no overlap of imports or code, I'm rather at a loss with what to try next. It only seems to affect Python-related scripts, although most of my work is Python. I'm leaning towards this being a Windows issue rather than a Python one given that the same code is running fine on other systems.
I'm using Python 3.7.0 on Windows 10.
Example display from Django code:
(venv) C:\Users\User\mydjangocode>python manage.py runserver Watching for file changes with StatReloader Performing system checks... System check identified no issues (0 silenced). January 05, 2020 - 11:54:02 Django version 3.0.2, using settings 'mycode.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CTRL-BREAK. (venv) C:\Users\User\mydjangocode>
There was around a five minute period after the line
Quit the server with CTRL-BREAK. was displayed before I tried to visit
127.0.0.1:8000. The script quit almost instantly as soon as I tried to load the page.
I've tried changing to a non-venv version of Python, with no effect.
I've checked Windows Event Viewer and there are a lot of recent error messages in there.

I've also tried upgrading to Python 3.8 with no effect.
I've run the system file check utility which didn't highlight any issues:
C:\WINDOWS\system32>sfc /scannow Beginning system scan. This process will take some time. Beginning verification phase of system scan. Verification 100% complete. Windows Resource Protection did not find any integrity violations.
I've also run CHKDSK which hasn't highlighted anything.
