It's possible that your recruiter quit and hopped to a different company. That is one common source for recruiter going dark. It's also possible you got a really bad recruiter... there's an enormous variance of recruiter quality.

Just guessing here, but auto generated emails are tricky because you don't want to send people incorrect messaging by accident (for example if your recruiter wants to swap you between application roles, it may involve a cancel and add, which could send an auto rejected notice - (hypothetical example, I have no idea)).
