Can't run example

[oOBoomberOo]

This error popup on every example project and even on my own iced project.

thread 'main' panicked at 'Unable to enumerate instance extensions: ERROR_INITIALIZATION_FAILED', src\libcore\result.rs:1189:5
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

Also, when I try to import module in VS code it doesn't seem to provide import suggestion for component (i.e. iced::button, iced::Element) but it does provide import to settings, Sandbox and Settings

System:
OS: Windows 10
GPU: Nvidia GeForce GTX 1080 (Up to date driver)
Version: iced = 0.1.0-beta
Rust: stable-x86_64-pc-windows-msvc

Got similar error with MacOS pulled from latest master branch.

Here is the stacktrace:

Thank you for reporting!

Just to discard an issue upstream, I'd appreciate it if you could try any of the examples in wgpu and see if the same issue happens there.

[oOBoomberOo]

Tested, seem to be wgpu problem.
It displays the exact same error.

[oOBoomberOo]

Actually, after following down the rabbit hole. The problem seem to come from the Vulkan itself.
I'll try updating/reinstalling the graphics driver and see if the problem go away.

[FuGangqiang]

I also got this error, The problem seem to come from the Vulkan itself,
archlinux wiki has some doc

[oOBoomberOo]

The issue is fixed after reinstalling graphic driver.
