All of the EINVAL checks in https://github.com/sctplab/usrsctp/blob/63d620ae9ab818cf51448c9ad0a04f9688c5f28b/usrsctplib/user_socket.c#L864-L889 look like they should pass, so I think this must be coming from lower in the stack.

One possibility for digging into this might be building gstreamer from scratch and modifying https://gitlab.freedesktop.org/gstreamer/cerbero/-/blob/master/recipes/libusrsctp.recipe to add the sctp_debug meson option.
