Crash since iOS 13.3.1 #4

This issue happens on the Demo app because some resources cannot be loaded.

Crashed here "Fatal error: Unexpectedly found nil while unwrapping an Optional value"

I just found out that the problem is somewhere in metal file, for example "MTHudsonFragment" in MTHudsonFilter.metal. I do not know what the problem is exactly. Thank you!

It seems that we can not init CIImage with PVR format texture in iOS 13.3.1.

I have change to load texture with MTLTextureLoader and seems to fixed that crash.

Everything look fine now and it is working as is should. Thank you and can you please guide me to some tutorial of kernel or how can I make my own custom filters?
