450 top end removal chasing the knocking

Hello. I finally got the motivation to take apart the top end to see If I can find what is causing the knock in the engine. What I have feared has happened. I did not find anything out of the blue. Unless I’m wrong and you can spot something…. Here is a YouTube video. Please any input would be greatly appreciated !

The problem is found.

The starter clutch worked its way to freedom. The bolts came loose.
