Davince Resolve closes without letting me save

So I was editting my video, and then Davince Resolve 16 just freezes and closes without letting me save. This has been happening all day, and it closes when I've finished editting and was about to save. This is very irritating and is wasting my time.

The crashing is a problem that should be solved, for sure.

The 'not saving' can be solved by turning on the Live Save feature. Every change you make is instantly saved, so when it crashes, you don't lose anything.
