Is there an existing issue for this?

• I have searched the existing issues.

What's the problem?

latest release on crates and brew:

thread 'main' panicked at /home/linuxbrew/.cache/Homebrew/cargo_cache/registry/src/index.crates.io-6f17d22bba15001f/iced_winit-0.12.2/src/application.rs:119:10:
Create event loop: NotSupported(NotSupportedError)

Hey @ngmisl, this seems to be an upstream issue.
The program is crashing at this line of the iced_winit dependency.
And this is the method that's causing the crash.

It's pretty weird that you're the first one to face this problem.
Can you please provide me with additional information about your OS and environment?
