Yuu can't determine the Reason for a RST packt from a packet capture. That information must be obtained from the system sending the RST packet.
Sometimes you can guess based on the packet that triggered the other party to send the RST packet. And in some cases additional information is in the RST packet.
But SYN/ACK/RST packets .... are rare.
Have a look at https://serverfault.com/questions/575650/why-would-a-client-send-a-rst-packet-as-reply-to-a-syn-ack
