Export is purple/green and then pc freezes

Hello, I have a windows pc with raedon 18.10.2 running, intel core i5-7400.

I just downloaded rush cc and I added clips, made a video and exported perfect. Went to make a second video and everything worked fine and then it exported with a green and purple haze over it (ruining one of my free downloads) Also, same type of clips as the first video (all from twitch.tv). Then I go to make a 3rd video to test it and it freezes then crashes my pc. After doing this 10 times I uninstalled and reinstalled the program. Great, works fine. But now it won't export without the haze again. My drivers are up to date (I checked again) and I didn't change anything from the first video to this one. Can someone help? This is a great program for me since I like them simple, so I wanted to test before buying.

I tweeted at adobe care and they told me to come here.

Thank you!
