Red Lines under all functions Follow
For some reason, PyCharm just started red underlining any function I write, even in a fresh project. The file still runs despite the lines. It was not doing this this morning so I must have accidentally changed some setting but I have no idea what that could be. Has anyone ever seen this before?

There could be too many reasons to start shooting randomly.
Let's start with **File | Invalidate Caches / Restart... | Invalidate and Restart**, if it's not helping, please show some screenshots of the issue and your project structure.
OK, here is a screen shot. Invalidating the cache did not work. This is a test project that I created just to see if I would get the red lines. There is only one file that has one function. Is there any possibility that a recent update to PyCharm has caused this?
For future reference for some poor soul in the future with the same problem, the answer is:
File | Manage IDE Settings | Restore Default Settings
That did it.
A word of caution to future poor souls from the poor soul that had this issue and resolved it with Restore Default Settings.
I should have expected it, but every config change I've ever made to my IJ environment is gone. It's got that new out-of-box smell...
This seems to be a safer first try:
