Bug When creating a game build, Unity crashes Windows how to fix it?

I have a major game that I've been working on nonstop for 1.5 years, it's time to release, I thought. The latest bugs, errors have been fixed, optimization problems seem to have even been solved, I start compiling the game, I wait an hour or two, and bam, Windows crashes, with what exactly after two hours of compilation. Amazing, I say, the engine has already become S***, and then there's this. Has anyone encountered this? And if not, then don't tell me where the engine debugging logs are, which it does when it compiles something, in order to at least see what causes Windows crash, thank you.
