Hi @Mykola-777. We don’t have a lot of examples where use with threading with UI updates. I would try to stick with coroutines if possible as that pattern is much more common in our code base. If you do need threads, I found a couple of examples in these extensions:
omni.isaac.onshapeomni.kit.window.audioplayer
Have a look at those. If you want to share some code, I can look to see if I can spot any problems.
