Yesterday everything was working fine, but since today I can't start Qgis anymore, because it crashes.
This affects all the versions that I have currently installed (2.8, 2.10. 2.12 and 2.14). The program loads and when it says "Starting Python", it crashes and writes a minidump (see screenshot below). QGis Browser launches normally.
What did I do yesterday: I used Grass (v.clean) and changed/cleared the folder paths for the plugin as explained in the answer to this question. Also I tried out something with a function in field calculator. But can all this cause all installed versions to crash at startup?
What could be causing this? Is there a way to manually fix this? I also tried a restart, but this didn't work. Edit: I use Windows 7 64-bit.

Okay, I found the solution.
The problem were Python expressions that I created yesterday to test something. I deleted them in the folder: C:\Users\xxx.qgis2\python\expressions
Now it works all fine again.
Maybe the expressions were wrong or something, kind of annoying though that it then kind of "destroys" the whole program even older versions of it.
