You can use Polyspace R2020b with MATLAB R2019a, but some functionalities are not available in a cross-release integration. See more details in Polyspace Support of MATLAB and Simulink from Different Releases.

The license manager error -9 is related to unactivated software. See, for example, Why do I receive license manager error -9. Can you answer a couple more questions to help us understand the issue:

• Are you able to run Polyspace outside of MATLAB? For instance, from the Polyspace UI or command line using the polyspace-bug-finder executable.
• Are you getting the license manager error -9 when running Polyspace function in normal mode? Or is it a different error? Which function were you trying to run and what was the error?

Is this true for any function or some specific Polyspace function?
