MATLAB: Is MATLAB R2020b not detecting a silent Support Package installation

I installed a Support Package silently with an offline Support Package download. When I open MATLAB, the support package doesn't appear to be installed when checking Add-ons>Manage or when running:
>>matlabshared.supportpkg.getInstalled

We are currently investigating an issue with the following file:
C:\ProgramData\MATLAB\SupportPackages\R2020b\sppkg_matlab_info.txt
This file is created during the installation process with an abbreviated path. The current workaround it to open the file in a text editor and modify the path to:
(R2020b)@C:\Program Files\MATLAB\R2020b
Please note this path is case sensitive within this file. Save the changes and restart MATLAB.
