Unity: Hang in "callback in NoesisLangServer"
Posted: 28 Sep 2025, 00:00
This doesn't happen often, but sometimes this chain of events takes place (on both Windows and Linux):
- Game is running.
- I modify a panel. In one case, I moved a Border containing a stackpanel and some buttons to a different grid.
- The modification triggers hot reloading.
- Unity deadlocks.
- I have to kill Unity.
- When Unity restarts, the scene load hangs with "waiting on callback in NoesisLangServer"
- This sits for about 30 seconds and then things are fine.
I don't have any more specific information, so I'm a little hesitant to make a bug report on it and I don't have a stripped down simple repro to share.
