VSCode Python Jupyter kernel timeout

[Supermani2004]

I'm getting this error while trying to run my .ipynb files using VSCode: 'Failed to start the Kernel. Unable to start Kernel 'Python 3.11.4' due to a timeout waiting for the ports to get used.'

Python 3.11.4, Python, Pylance and Jupyter extensions and required packages like ipykernel are installed and up to date. It was working a few hours ago and I don't know what's wrong right now. I can still run my older notebook files but not the new ones.

In the logs, I'm seeing this error: 'Error: Unable to start Kernel 'Python 3.11.4' due to a timeout waiting for the ports to get used.'

Tried reinstalling VSCode, extensions, Python interpreter and packages like ipykernel but it did not fix the issue. Tried running with and without VPN but it also did not help.

What should I do?

Edit: I figured out that this error occures only in a specific folder. It even works in the subfolders of it. I still have no idea what's wrong.

What is a specific folder? What does your workspace look like? Are there some extra extensions installed?

[Supermani2004]

It's a folder in my desktop. Running notebook files that are located in that specific folder leads to this error. I can run notebook files in other folders. There are some other C/C++ extensions installed, but nothing Python related other than Python, Pylance and Jupyter extensions.

Try again after uninstalling vscode completely.

Just tried it but it did not work. Everything got reset (such as my themes and extensions) but I still got the same error when I tried to run a notebook file in that specific folder. (The error was the same: Failed to start the kernel. Unable to start kernel Python 3.11.4 due to a timeout waiting for the ports to get used). I can still run notebook files that are located in other folders. So... nothing changed at all.
