Simulink 2018b errors

We have a simulink model on Matlab 2018b that we were using successfully but now we get the following errors in matlab (we have not made any changes to the model). There are a lot so I will just send a snippet of some of them.

Thank you for your help!

Hi @Tanaya, Could you tell me which platform and operating system you are currently using?

Also, please refer the MATLAB Answers link to a similar issue, which might help to resolve the error.
