DaVinci Resolve 17.1(Free) not opening or playing files

I am a new user of DaVinci Resolve software and I am trying to decide if it is for me.
For starters I installed ver.17(beta) on my Windows 10 workstation and it was working fine and opening .mp4 and .MOV files that I was trying to edit, then when I upgraded to 17.1 the software would open normally but I wouldn't see the previews and the video loaded to the timeline wouldn't play.
To test further, I installed ver.16(stable) and everything went back to normal. Then I updated from 16 to 17.1 and the issue came back again.
I know i don't have the best PC configuration for 17.1, but I believe my hardware covers the basic requirements to run 17.1 (based on Blackmagic's website)
Please advise.
Thank you,

Windows 10 (Home) 64 bit on Samsung SSD 840 PRO
