The version of matlab is shown in the right column, which is R2019b. Yes I have tried to restart and open the model the following message is shown (I believe they are the same):

for class slreq.app.PerspectiveManager:

Hello Enrique,
I understand that you are encountering errors while trying to open the ‘Requirements Manager’ app from the ‘Apps’ tab in MATLAB.
In this case, as a workaround, you can try opening the Requirements Editor using the following command in MATLAB R2019b:
slreq.editor
For more information on opening Requirements Editor, you can refer the following link: https://in.mathworks.com/help/releases/R2019b/slrequirements/ref/slreq.editor.html
Further, you can also try upgrading to MATLAB R2022a or a later version and use anyone of the following options:
1) Use the ‘slreq.openRequirementsManager’ command. An example for this is given below:
open_system('model_name');
slreq.openRequirementsManager('model_name');
For more information, refer this link:
https://in.mathworks.com/help/slrequirements/ref/slreq.openrequirementsmanager.html
2) Open the Requirements Editor app using any of the following ways:
a) Simulink Toolstrip: On the ‘Apps’ tab, under ‘Model Verification, Validation, and Test’, click ‘Requirements Editor’.
b) MATLAB Toolstrip: On the ‘Apps’ tab, under ‘Verification, Validation, and Test’, click ‘Requirements Editor’.
c) Type this command on MATLAB command prompt,
slreq.editor
For more information on the same, refer the link below:

I hope this helps.
