Windows client crashes when starting stream while in call with Fedora user running Flatpak package

User A (Windows) and User B (Fedora Workstation running the Flatpak version of Fluxer) join a voice call. User A (Windows) starts a screen share/stream. User A's Windows client immediately crashes.(Note: Repeating this when User B uses the native RPM build of Fluxer does not cause a crash).

User A's Windows client should start the stream smoothly without crashing, regardless of which package version the receiving participant is running.

The Windows client crashes immediately upon starting the stream whenever a participant in the call is running the Linux Flatpak version of Fluxer.
