Replicable [object DOMException] after external user stops screen sharing

[Stay1444]

discord-screenaudio encounters a DOMException when this specific steps are followed:

1. Start discord-screenaudio
2. Screen share
3. Stop screen sharing
4. Windows user starts screen sharing
5. You open and watch their screen share
6. They stop screen sharing

Now you get the Discord has crashed! Screen but you can still hear and talk, it's just the interface that has died.

This are the relevant logs, i can't seem to open the electron inspector to see the actual DOM exception:

Verified. This happens to me aswell

Hm, I can not reproduce this, although I also didn't try a windows machine, but just the official discord client on Linux. Can you figure out the exact exception through remote debugging? For that, start discord-screenaudio --remote-debugging and open http://127.0.0.1:9222 in a browser of your choice.

It's weird. For some reason only happens when a Windows user stops screen sharing. I think this is the error that causes the crash

And then this appears

The errors are not that useful (?) i think because the sources are minified and what not. Let me know if there's anything else I can do.
