Code Snippet

rpm_max = 3200  # [tr/min]
print(rpm_max)

Expected behavior

Variable rpm_max should not be grayed out

Actual behavior

All variables in my file are grayed out (but no error anywhere). I reloaded, reinstalled, reenabled the extension. Some times the issue disapear (no more grayed variables) but as soon as I add a new line, they all get grayed again.

My extensions are:
alefragnani.project-manager
ms-python.black-formatter
ms-python.debugpy
ms-python.python
ms-python.vscode-pylance
ms-toolsai.datawrangler
ms-toolsai.jupyter
ms-toolsai.jupyter-keymap
ms-toolsai.jupyter-renderers
ms-toolsai.vscode-jupyter-cell-tags
ms-toolsai.vscode-jupyter-slideshow

I wasn't able to repro. Does the issue repro for you with just those two lines of code?

No the whole script is like that. Here is a gif of another section. Everything is fine when I open the script, but as soon as I edit something it happens again.
