Crashes in the game Dota 2, what to do?

I often encounter the problem of crashes in the game Dota 2, and it prevents me from playing normally and enjoying the experience. Every time the game suddenly closes, I lose progress in the match, which is frustrating and spoils the impression. I don’t understand why this happens, and it’s hard for me to figure out the reasons. This creates a lot of inconvenience, especially when I’m playing with friends.
