Hey Ashwin,
The following MATLAB Answers post by MathWorks Staff goes into the steps on how to solve the cache issue:
https://www.mathworks.com/matlabcentral/answers/2142116-how-to-resolve-the-error-could-not-access-matlab-runtime-component-cache-fl-filesystem-invalidargum
It seems like the MATLAB Runtime cache was corrupted and needs to be cleared. If that doesn't solve it, the post also notes to get in touch with MathWorks Support, which can be done from the link below:

Hi Jacob,
Thank you for your response!
The links you provided explain how to resolve the issue when Polyspace Bug Finder is installed as an application. However, our situation is different as we are using Polyspace within a Docker container for report generation. No worries, I'll reach out to MATLAB support for assistance.
Regards,
Ashwin
