XPS 15-9570, completely freezes randomly

My Dell XPS 15 9570 just completely freezes randomly multiple times a day (usually when I leave it IDLE) to the point that I have to force shutdown. I thought the problem would eventually go away after a few days, but it happens more and more often as time passes. It's extremely annoying, as I use my laptop mainly for school and I often have unsaved work because of this issue. It freezes more than 6 times a day and it makes the laptop unusable. I've tried contacting support and they have not been helpful at all: they only asked me to run hardware tests, which showed no issues and ask me to update all my drivers that were already up to date. They then told me that the warranty only covers hardware issues and that I would need to pay to get assistance with the software? What am I supposed to do now?
