Think I was able to reproduce it. I configured my router to drop established connections for IP 169.150.221.147 in my policy attached to my wan interface for outgoing traffic (important detail, inbound would drop the syn/ack instead). For reference its an Ubiquiti Edgerouter that uses iptables to filter traffic.
In the linked picture [0] I have packet #436 selected, its a retransmission of the handshake syn/ack with seq=0 ack=1, repeating a few times later, same as OP.
So as others suggested, likely a misconfigured BOGON rule with 169.0.0.0/8, but also matching outbound established connections rather than new/any state for some reason.
