Dyson ball 52 stops sucking one second after turning on

The main part of the vacuum has strong suction when no hoses are attached. Once I attach the flex hose, the suction greatly decreases and the is almost non existent.

I've check all hoses/attachments for blockages, took apart the main housing and found no issues, and also opened up the post filter attachment.

When I turn the unit on (with any hose attached), it works for 1 second then sounds like something is sucked into some sort of blockage.
