DaVinci Resolve Crashing

I've been using DaVinci Resolve 16 for quite a short time and I thought that I had a good hardware for this editor, but, it turns out that sometimes when I hit play it takes a few secods (which I don't mind, just for the record) and mostly that it crashes while being on the cut workbench, and I don't understand why. If there's any way of optimising or solving this, would be much apriciated. Everything I've touched is playback, where I've proxy mode on a quarter resolution and automatic caché rendering. Also, most of the clips I use are mp4, idk if that influences.
