I was making a house in blender using a tutorial. I have not messed with the settings I have only ever added some addons. Today when I went on blender and tried to extrude a circle it did not work and gave me a really long error message. I reset my factory settings and reinstalled blender it still didn't work, so I looked in input just in case it was something to do with that but the whole input box is black. I also checked to see if the same thing as happening on the steam version of blender nothing had changed.I installed a beta version of flip fluids from GitHub but it had lots of python files so I installed all of them, it doesn't show up as an addon though.
first part of error message
Thank you for your help!
(edit: everything is fine on blender 2.80)
