I track my app ratings and it does not change even though I got new ratings from my friends. This happens since January. Is there a known problem? Any suggestion?

I try to run mlmodel prediction and I get below error: /Library/Caches/com.apple.xbs/Sources/MetalImage/MetalImage-124.0.29/MPSNeuralNetwork/Filters/MPSCNNKernel.mm:752: failed assertion `[MPSCNNConvolution encode...] Error: destination may not be nil. I use IOS 14 and implement the same method. I attach the screen shot of the code where error occurs: Appreciate your advice mlmodel's swift file screenshot where error occurs - https://developer.apple.com/forums/content/attachment/1117d26a-6db8-4cbd-9d5e-616aac7ad308
