unknown file type returned by export dialog

Using version 3.6.2 I am able to filter a call trace, mark all displayed packets and export specified packets to a new file but that functionality is not working in newer versions. Attempts to do so result in the error, "unknown file type returned by export dialog". I have tried Wireshark-win64-4.0.10, Wireshark-win64-4.0.10, Wireshark-win64-4.0.12, Wireshark-4.2.0-x64, and Wireshark-4.2.2-x64. This is an issue because I need that functionality on a regular basis but our organization requires that we use v4.2.0. Please advise and thanks.

What's your source capture file type, what's your destination file type? Just tried it with PCAP files, and it worked as expected.

Jaap -

Source and destination file types are both .pcap in this case using Windows 11. Are you also using Windows and, if so, what version of Wireshark did you use for that successful test?

This was tested on macOS. However, as Guy noted in the answer below, please file an issue with full details.

It also results in the text

"Please report this as a Wireshark issue at https://gitlab.com/wireshark/wireshar..."

in the same error dialog, because, as a comment in that part of the code says:

/* This "should not happen". */

so this is a bug.

Please report it as such, and include all the details.
