Baby screaming at bedtime

I don’t know what is going on but my 6 month old is SCREAMING uncontrollably when we lay him down for bed. He has just finished the 5th leap so what is this??

Perfectly fine until I set him down. Patting him, singing, etc doesn’t do a thing. Spits the paci out. He thrashes around like he is being tortured all of a sudden.

I’m at a complete loss. It takes hours to put him to bed now and then he wakes up multiple times doing this throughout the night. My husband and I are so on edge.
