I have just tried to upgrade everything in my main environment to the latest version (using conda update --all). Everything went completely fine until I actually tried to run python. I got this error message:
Traceback (most recent call last):

As you can see, it looks like a problem with sys.flags. I tried googling this, but I couldn't find anyone with the same issue. I am using python 3.6.7 (python didn't update itself). This error message also appears if I try to run python in the command prompt. Here is the output of running conda update --all. Hope you can help!
EDIT: I found an issue on this issue on github here, but this doesn't give any explanations on how to fix this.
NOTE: I have also tried to install a new version of python using the installer, but that didn't work either.
I somehow did it - I re-installed Python, and then I tried using the command prompt, and it worked. It turned out that if I deleted my idea folder in Pycharm, it would work with the new version!
