Hello Salah,
I understand you are facing some issues while opening the Simulink model with R2021b.
Please follow the below workaround to resolve the issue:
  • Modify the search path and clear the cache: Before modifying the search path, it is important to take a backup of your 'pathdef.m' file, which can be located by using the command:
>> which -all pathdef
Before proceeding, ensure that you make a safe copy of the file by copying it to a folder outside of your MATLAB path.
After taking the backup, execute the following commands in the MATLAB Command Window to restore the default MATLAB search path and rehash the toolbox cache:
>> restoredefaultpath
>> rehash toolboxcache
>> sl_refresh_customizations
After this step, use Simulink to see if the issue occurs again. If the issue is resolved, then you may want to save the new MATLAB search path by executing the following command:
>> savepath
NOTE: This will remove any custom paths you may have created. The following MATLAB Answers post is an additional resource on how to back them up:

  • Regenerate MATLAB preferences: Go through the following MATLAB Answer link to understand the workflow:

I hope the above workaround resolves your issue, else, please contact Technical Support
