It appeared green stripes on the preview screen

I had the exact same issue around playing back MXF files in Premiere Pro with this Nvidia driver: 451.48.  Also the same issue in Multicam Window with this driver.  Other video formats were fine but MXF files had sever picture disturbances (small little graphical blocks on screen).  Media Encoder also exported MXF files with all the disturbances.  DO NOT install the latest Nvidia Driver 451.48 - you WILL battle with certain video files (MXF in my case) in Premiere Pro CC.  Reinstall Driver 446.14 - still works like a charm!
I have Windows 10 Pro, 64GB RAM, Adobe Premiere Pro CC 14.30 (Build 38), NVidia GTX 1080 Graphics card.  I had to go back to NVidia previous driver 446.14 to resolve the issue.
I assume NVidia/Adobe will look into this issue.

If that doesn't work, try creating a new project and import the old one into it.
