Error using sdi.Repository Database operation order error in. (unknown)

When I attempt to open Performance Advisor, the "Initializing..." window pops up briefly and then I get an error window popup with a "Database operation order error in. (unknown)" error. I'm using Simulink Real-Time 2015b.

When opening the Performance Advisor through the Model Advisor, I get the following error messages in the MATLAB Command Window:

Error using sdi.Repository
Database operation order error in . (unknown)

Error in ModelAdvisor.Repository/connect

Error in ModelAdvisor.Repository

Error in Simulink.ModelAdvisor/getWorkDir

Error in Simulink.ModelAdvisor/init>checkIfNeedLoadSlprj

Error in Advisor.Application/updateModelAdvisorObj

Error in performanceadvisor_exe

Error in performanceadvisor (line 18)
performanceadvisor_exe(system, varargin);

Error in Simulink.ModelAdvisor/displayExplorer>MECallback

Warning: Error occurred while evaluating listener callback.

I have tried clearing the repository (sdi.Repository.clearRepositoryFile();) but I still get the same error.

I ran into the same problem using Matlab R2016b on Windows for the Performance Advisor and the Model Reference Conversion Advisor. Providing the answer for others stumbling across this thread, even though it is rather old.

The error appears when the path is too long and some cache files cannot be stored. It can be solved by reducing the length of the path name.

This link references to the equivalent error message that I got in Matlab 2018b, which is answered by the Matlab staff.
