Recently my Vegas Pro has been acting really weird. My preview outta nowhere just glitches and changes colors to this:

Normal clip:http://prntscr.com/ktsoeg

It also turns all black from time to time even when I render it and It's so annoying.

My project settings:

My render settings:

Bitrate: 360.

I currently use Vegas Pro 16 and tried switching to Vegas Pro 14 and 15 but nothing helped. If anyone could help me out I'd be very grateful.

Thank you.
