ELI5 when a computer program freezes, why can’t the program automatically restart itself instead of someone having to manually force quit and restart it?

The program almost certainly doesn't "know" it's frozen. In order to respond to an error causing the program to freeze the developers would have to know about the error and write code to handle it. Why, if they know about it, would they do what you suggest rather than fixing it or otherwise handle it more gracefully than the program freezing?

Your operating system likely "knows" the program is frozen, but the OS doesn't make the assumption that a user wants to kill and restart a program immediately when it freezes because, often, you don't.
