I am getting the following error, I gave permissions also to read and write both in C:\Program Files\MATLAB and Users folder but this error occurs again. I am using MATLAB R2020a.

This error may been seen if the Web App Server Windows service is in fact installed but its corresponding configuration files on disk are missing or corrupted. If this happens you will need to perform a manual uninstall of the service and then reinstall using "MATLABWebAppServer.exe". To manually uninstall:
1. Open a Windows cmd.exe prompt with administrator rights.
2. CD to the bin\win64 directory of the MATLAB Runtime you are using in combination with Web App Server, for example:
cd "c:\Program Files\MATLAB\MATLAB Runtime\v98\bin\win64"
3. Run:
webapps_setup -uninstall
4. Using your favorite file management tool go to:
(You should be able to just literally paste this in for example Windows Explorer's Address bar, it should recognize %PROGRAMDATA% and automatically take you to the correct location).
Delete the directory corresponding to your MATLAB release, e.g. "R2020a"
