Why are you saying that this thread does not exist?
Could you add a bit more context to this issue, in its current state we will not be able to investigate it properly.

All the information the app provided me is in the screenshot :(

There's zero events in the thread, but it was saying I hadn't read it. It was fixed by manually sending an unthreaded read receipt for the room.

It was fixed by manually sending an unthreaded read receipt for the room.

@turt2live worth noting that right clicking a room and clicking Mark as read would do this too, no need to wrangle things manually.

Yeah the logs definitely show $Em9tLXv9GQG3d2iLqrrftQxZoMuzVFl6VdKgtJHe31U being treated as a thread - including (successful) calls to /relations m.thread for it.

"$Em9tLXv9GQG3d2iLqrrftQxZoMuzVFl6VdKgtJHe31U":{"events":["$Em9tLXv9GQG3d2iLqrrftQxZoMuzVFl6VdKgtJHe31U"],"numTimelines":1,"liveTimeline":1}

@turt2live can you share the unsigned from a GET https://t2l.io/_matrix/client/r0/rooms/!YTvKGNlinIzlkMTVRl%3Amatrix.org/event/%24Em9tLXv9GQG3d2iLqrrftQxZoMuzVFl6VdKgtJHe31U request?

I've unfortunately had limited success with this :(

{
  "type": "m.room.message",
  "event_id": "$Em9tLXv9GQG3d2iLqrrftQxZoMuzVFl6VdKgtJHe31U",
  "unsigned": {} // this is what you asked for :p
  // irrelevant event fields removed
}

worth noting that the UI was not showing any threads to me: nothing in the timeline, and nothing in the threads list, even after a reload.

This looks identical under the hood to #25480
