System Information
Windows 10 GTX 970 (driver v: 398.82)

Blender Version
Broken: blender2.8 - 2018-08-06 02:54 - f7b1fec463
Worked: Unable to pinpoint exact version as buildbot downloads since 6/4/18 have been deleted

Short description of error
When ever an add-on attempts to load, a traceback error popup comes up. There is a special case of cycles where it still shows up as a render engine, but whenever render mode is entered, blender instantly hard crashes as I'm guessing the actual engine failed to load.

When pressing some hotkeys that changes the mesh ( for example extrue) shows a traceback error popup. Note that this does not happen when trying to use something from the T panel. (same thing happens in node editor when creating new node from Shift+A but not when duplicating)

Exact steps for others to reproduce the error
Addon failing to load:

open settings
enable any 2.8 add-on

Edit mode hotkeys:

Enter edit mode
press E

Blend file: untitled.blend

Full output log for trying to render something in cycles: https://pastebin.com/ji1PC2Ne

Can't redo this: Does it happen if you run: import enum in the Python console? (instead of enabling the addon)

Well I'm sorry to say but I'm unable to do this as i'm completely locked out of the python console or text editor.
This error instantly happens when I open the scripting workspace and after that when I click or do a key down or bizarrely when I move the window.

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Is there any other way I can do this? I have blender ready in visual studio, although I have to warn that I'm not that experienced with C++ or Python.

Seems like there is something broken about your Python installation then.

Moving this to unconfirmed since many people would report this if it were common.

Alright so as an update to this... I found out what was the problem.

I somehow managed to put an addon source (as individual files) in the addons folder in user preferences. Once I deleted it everything was working fine.
This is an error on my behalf so it's not a blender problem. (unless you want to make it foolproof)
