It seems that the new version of coroutines 1.10.0 completely breaks Compose apps on wasmJs. The effect is that when you click on a button (or anything else that is clickable) and you make sure not to move the mouse while doing so, the whole UI will freeze. The action associated with the click will be delayed until you move the mouse a tiny bit. I tested this on Firefox, Chrome and Safari on macOS. Could you please provide some feedback whether you can observe the same behaviour on your OS?

If you open browser's developer console, you'll see a lot of errors.

Ah, then it is the same as your report:

Everything works again with the coroutines hotfix release 1.10.1.
Many thanks for the quick solution.
