wgpu error: Validation Error

Caused by:
In Device::create_bind_group, label = 'mesh_view_bind_group_binding_array'
Texture binding 0 expects dimension = Cube, but given a view with dimension = D2

Encountered a panic in system `bevy_pbr::render::mesh_view_bindings::prepare_mesh_view_bind_groups`!
```
EDIT: This is an issue with the Environment Light Map

Start at bevy_pbr::render::mesh_view_bindings::prepare_mesh_view_bind_groups and reproduce with the reported Bevy 0.17.3 default and exr features using the Environment Light Map. Trace how its invalid texture view reaches wgpu's create_bind_group validation, then verify that the resulting diagnostic is helpful instead of the current panic.
