Sounds like you need to tighten the clutch or a slipping clutch to me. I assume when you say your chain is moving you mean it is moving a little and not going at a considerable speed. There are many YT videos on adjusting the clutch and etc. Here is one that might pertain to your situation without knowing further details.

there is a woodruff key at both ends of that shaft - open both covers and see which side isn't turning
