My videos are all green and purple? How do I fix that...

So when I import videos into either premiere rush or Premiere Pro, all of the videos appear green and purple and they're all out of sync with the sound and they spazz out as if they're getting hacked into by some alien. Even when I make a video on my phone with Premiere Rush, and then work on the project on my computer, it changes to this. Any ideas of how to fix it?
