wgpu_hal problem

[FALLfield]

When I am running the example of 2D shape, there are some errors:
ERROR wgpu_hal::auxil::dxgi::exception: ID3D12CommandQueue::ExecuteCommandLists: Using ClearRenderTargetView on Command List (0x000001EB6DBDB290:'Unnamed ID3D12GraphicsCommandList Object'): Resource state (0xBF53EAF0: D3D12_RESOURCE_STATE_[COMMON|PRESENT]) of resource (0x000001EB6DAEDFD0:'Unnamed ID3D12Resource Object') (subresource: 0) is invalid for use as a render target. Expected State Bits (all): 0xBF53EAD0 : D3D12_RESOURCE_STATE_RENDER_TARGET, Actual State: 0xBF53EAB0: D3D12_RESOURCE_STATE_[COMMON|PRESENT], Missing State: 0x4: D3D12_RESOURCE_STATE_RENDER_TARGET. [ EXECUTION ERROR #538: INVALID_SUBRESOURCE_STATE]
My computer is AMD radeon GPU and some people say use WGPU_BACKEND= vulkan can fix this problem but I don't know how to do that.

If you are on Windows run
set "WGPU_BACKEND=vulkan" && cargo run --example 2d_shapes

[DasLixou]

For powershell, $env:WGPU_BACKEND="vk"; cargo run --example 2d_shapes.

How can I just set it to be vulkan without env variable?

App::new()
        .add_plugins(DefaultPlugins.set(bevy::render::RenderPlugin {
            render_creation: bevy::render::settings::RenderCreation::Automatic(
                bevy::render::settings::WgpuSettings {
                    backends: Some(bevy::render::settings::Backends::VULKAN),
                    ..default()
                },
            ),
            ..default()
        }))
        .run();
