Constant crashing in Resolve 14

Hello,
I'm constantly crashing in Resolve,
This happens in a project where I have multiple clips and didn't happen when I was grading single clips.
I'm not running any nodes or effects, simply editing.
The crashes occur during playback, it seems the clips don't "cache" properly, even when I give it time (30 sec)

I'm using R14 with Windows 10, 16GB RAM, AMD RX480
I have the logs but for some reason the forum says I can't post URLs

Does anyone know why this could be happening?
thanks

Put the DaVinci Resolve diagnostic logs on dropbox or the like and provide a link here with a space in the path so it doesnt look like a link to the computer but is human readable.
