I have just downloaded DaVinci Resolve 17 so that I can edit my first video. I boot up the editor, place my .mov, place it in the timeline; and boom! I see no video nor audio being played back!
Example of issue:

System Info:
CPU: AMD Ryzen 7 2700
GPU: Radeon RX 580
Motherboard: Gigabyte B450M DS3H WIFI-CF
Please Help if you can. If you need more info, just say it!

(P.S. I this is my first time using resolve so I may be doing something wrong here with the application itself)
