Previously accessible file is now inaccessible.

The IT upgraded my matlab and I keep receiving this error when I want to open an existing file.

Previously accessible file "C:\Program
Files\MATLAB\R2019a\toolbox\shared\reqmgt\+slreq\+data\@ReqData\ReqData.p" is now
inaccessible.

Error in slreq.utils.loadLinkSet

Error in rmiml.getAll

Have you asked your IT?

Try using the following command which may solve your problem.

rehash toolboxcache; 

For more information, refer the following link: https://www.mathworks.com/help/matlab/ref/rehash.html

Thanks Abhilash. It solved the problem. However, I still get this error message when I open matlab.

Undefined variable "slreq" or class "slreq.data.ReqData.exists".

I have the same issue. All I did was finish my AppDesigner app, then move the app and its dependencies into a new subdirectory called "src". Then when I cd into that subdirectory and try to run AppDesigner again on it, it will load into AppDesigner fine, and the preview looks fine, but when I click "Run", I get this same error in that somewhere inside the execution space, the old location of my app is being looked for. It seems that a hard-wired path that gets inserted into the *.mlapp code that gets corrupted if you move the *.mlapp code to another location.

This is my problem too.
