Not able to access Reinforcement Learning Toolbox in R2019a

I am trying to use MATLAB inbuilt examples of Reinforcement Learning.But getting an error that says "Require Reinforcement Learning Toolbox".

Can anyone please help?

Folder where MATLAB is installed shows all .m files related to RL toolbox still why this kind of error?

Someone else recently had the same issue. Their license appeared correct and the files were found for them. All we could suggest was to contact Support

If I try to go to Add-Ons and check RL toolbox, it shows "installed". Is it require to configure different license for different toolboxes also?

I would also like to know, is it possible to use python RL codes in MATLAB 2019?

i have this problem when writing

>> env = rlPredefinedEnv('CartPole-Discrete')

'rlPredefinedEnv' requires Reinforcement Learning Toolbox.
