[2022] rainbow is not working, at all.

Hey there @KILLEZONE51,

I know a game not launching properly is frustrating so I'm really sorry you're having some trouble with it.

I'd recommend making sure that your game is installed on the same drive as your launcher(s) and clearing your Ubisoft Connect cache. 
After, run through the quick steps from our basic technical troubleshooting guide.

If that doesn't help, go ahead and create a Support Case with us and attach your System Files. Let me know after this is done and I'll use those files to see if we can figure out what's causing the crashes to happen.
