Sometimes I get really annoying errors that just come randomly, probably from a failed conversion to Unity 5, and I double click and it won’t open up Visual Studio (or Mono w/e)!
There’s no hint or indication what app or plugin is causing this. I’m currently cutting 1/2 my files at a time out of the project and pasting it anywhere randomly, seeing if error persists (This ONLY works if error occurs before hitting play or you dig a deeper hole), then CTRL+Z and wait 45 mins to reimport all the assets and continue the trial and error.
Of course it’s my fault that I had an import frenzy, but it would be nice if I could at least find out where this is coming from. Gah… maybe I’m just venting
