Im getting these errors on compiling

Error in port widths or dimensions. 'Output Port 1' of 'topModel_DeepRL5/AWGN Channel/Random Source' is a one dimensional vector with 1 elements.

Error in port widths or dimensions. 'Input Port 2' of 'topModel_DeepRL5/AWGN Channel/Dynamic AWGN' is a [5x1] matrix.

I have MATLAB 2020b installed. But when I installed Communications toolbox, it prompted me to install it from R2021a. Im afraid that could be the possible issue here. How do I install R2020b version of this Communications toolbox?

Would it be possible to share the model - i'd like to see how the signal propagation is occuring. From the cited graphic, i see a [5] input and output from the AWGN block. Feel free to call in to support if needed.

It does not seem likely that the release versions would have caused this issue.
