The behavior of this workflow on this version of Unity, while not ideal, is not crashing or hanging and is undefined. Currently, a window that closes by itself will open the modal and then proceed to close the whole chain.
2022.1 no longer receives updates. Please update to 2022.2 or higher.
This issue is fixed in newer versions of Unity and is too risky to backport at this time.
How to reproduce:
1. Open the attached user project “ModalWindowFromAuxWindowEditorFreeze.zip“
2. Open the “Aux Window“ window (Bug Report>Open Aux Window)
3. Press the “Open Modal Window“ button
4. Un-focus the Unity Editor window
5. Focus on the Unity Editor window
Expected result: The “Modal Window“ window is shown, it is possible to close the window and continue using the Editor
Actual result: The “Modal Window“ window isn’t shown, the Editor is unresponsive
