Having issues since updated to Matlab R2020a Update 6

I have been getting the following since the day I updated Matlab version R2020a to update 6.

• Unrecognized function or variable 'matlab.internal.addons.updates.fileexchangeaddon.getTypeFromPackageInfoUrl'.

And on using smimport I am getting the following errors:

• Loading C:\Program Files\MATLAB\R2020a\bin\win64\simulink_plugins\sl_sysarch_modelsync_reg\libmwsl_sysarch_modelsync_reg.dllfailed with error: The specified procedure could not be found. : state not recoverable: state not recoverable (This was solved after I followed the steps in a previously asked question to a similar error.) After this I am getting the following error:
• Loading C:\Program Files\MATLAB\R2020a\bin\win64\simulink_plugins\sl_sysarch_modelsync_reg\libmwsl_sysarch_modelsync_reg.dllfailed with error: The specified procedure could not be found. : state not recoverable: state not recoverable

Solved by Clean Re-install of the same.
