`std::bad_optional_access` error in `Session::ProcessCommit`

[KubaZ2]

I am reporting this on behalf of a NetCord library user and I have not been able to reproduce this issue on my machine, it seems to happen randomly

Session::ProcessCommit sometimes throws std::bad_optional_access causing a commit to fail.

std::bad_optional_access from DAVE seems to also be included in this bug report: discord-net/Discord.Net#3251. That means that others seem to also get that issue.

Logs

An MLS error occurred: discord::dave::mls::Session::ProcessCommit bad_optional_access
