Wireshark 3.0.2 seems to expect TLS 1.3 Hello Retry Messages as specified before draft-ietf-tls-tls13 version 22, and not the current version of the RFC 8446.

Specifically, as far as I can tell, before version 22, the Hello Retry Message was much simpler than after that version. It had just the protocol version, cipher suite, and extensions. Since version 22, the message is pretty much the same as the Server Hello including a (non-random) random field, compression method, etc.

By the way, there is something that might be related in comment #83 for Bug 12779, but I don't understand what this comment is about.

What am I missing?
