How to resolve the error "Could not access MATLAB Runtime component cache fl:filesys​tem:Invali​dArgument"​?

I am attempting to run a compiled application. However, I am encountering the following error:

Could not access the MATLAB Runtime component cache.
Details: fl:filesystem:InvalidArgument; component cache root:;
componentname: APP_NAME

How can I resolve this error?

This error indicates a corrupted MATLAB Runtime cache for this application. Please try the following:

1) Please delete the application cache root folder by following 

How to Clean the MATLAB Runtime (MCR) Cache? - MATLAB Answers - MATLAB Central (mathworks.com)

.

If the error comes from a MATLAB Web App Server application, its default cache folder is "C:\ProgramData\MathWorks\webapps\<release>\USR\.appCache\mcrCache<version>" on Windows.

Then restart the application.

2) If step 1 does not resolve the issue, create a new system environment variable "MCR_CACHE_ROOT" with a value such as "C:\Temp", then restart the application. This should resolve the issue. Note that you may need to log out and back for the environment variable change to take effect. See Documentation page for more details 

MATLAB Runtime Component Cache and Deployable Archive Embedding - MATLAB & Simulink (mathworks.com)

.

3) If neither of these steps resolve the issue, set the following environment variables, log out, log back in, and then launch the application. Please reach out to MathWorks Technical Support with the resultant log file to determine cause and possible solutions.
