Fatal error: Unexpectedly found nil while unwrapping an Optional value

Error Description: "GPUImage/MetalRenderingDevice.swift:41: Fatal error: Unexpectedly found nil while unwrapping an Optional value" iOS Version: 14.5

When init camera, my app will crash and console show log as above. iOS 13.x is ok, so I guess maybe we should update framework to adapt new iOS 14.x ?

@whtoo Have you worked out what the issue is with this? Im getting this error also on 14.X
