Code is panicking, with exit code 0xC000041D when attempting to allocate command buffers

[bzm3r]

I know roughly what operation causes the panic due to step-through debugging:

ash/ash/src/device.rs

Line 2487 in 51f5997

let err_code = (self.device_fn_1_0.allocate_command_buffers)(

Can I have some guidance on how to debug this further?

It turns out that a Vulkan Instance I had created was being dropped too early, even when it was still being used.

The solution was to keep it around in a GpuState struct I am using to hold various bits of GPU-relevant state.
