Steps to Reproduce

It randomly happens and I cannot find a way to reproduce it at the moment.

Versions

• keyboard-layout 2.0.17
• Electron 16.0.4
• macOS 12.0.1

Additional Information

Looks like the exception happens via KeyboardLayoutManager::HandleKeyboardLayoutChanged.
I haven't changed the keyboard layout but perhaps it is invoked when switching between English to Japanese input?
I'm using Google Japanese Input.
I would be happy to contribute. Please let me know where to fix.
