The parser is right, the brackets are not allowed in the Via received parameter, "received=[2a01:7a0:3::2]" is incorrect.
https://tools.ietf.org/html/rfc3261#section-25.1
via-received = "received" EQUAL (IPv4address / IPv6address)
where
IPv6address = hexpart [ ":" IPv4address ]
hexpart = hexseq / hexseq "::" [ hexseq ] / "::" [ hexseq ]
hexseq = hex4 *( ":" hex4)
hex4 = 1*4HEXDIG
Note that the value of the parameter can be an IPv6address, not an IPv6reference (IPv6reference = "[" IPv6address "]").

Betreff: [Newsletter] parse error with IPV6 addresses in square brackets
Gesendet von: "pjsip" <pjsip-bounces@xxxxxxxxxxxxxxx>
Since asterisk 13.13, it does not recognise IPV6 SIP packets produced by
AVM Fritz OS any more.
It looks like this is related to the parsing of square brackets.
It says:
"PJSIP syntax error exception when parsing 'Status Line' header on line
2 col 112"
col 112 is: [2a01:7a0:3::2]
^
As you can see, the INVITE responses are not being processed, this
breaks my SIP installation. I wonder if anyone has also observed this
behaviour and if there is a known resolution for it?
