While everything worked fine a few days ago, when I now try to launch Simulink R2022b, it fails with an error similar to the following:
Failed to load bundle #474: C:\ProgramFiles\MATLAB\R2022b\bin\win64\dastudio.dll

This issue is commonly caused if antivirus software suspects that a file from your MATLAB installation is harmful and quarantined it. In this particular case, users reported that Avast or AVG antivirus software has detected a "Win64:Evo-gen [Trj]" threat inand thus quarantined that file.
C:\Program Files\MATLAB\R2022b\bin\win64\libmwxtester_core_mi.dll
By using a service such as https://virustotal.com, it can be verified that many other antivirus tools did not find a threat in that DLL.
To resolve the issue, open your antivirus software, navigate to the "Quarantine" menu, and release libmwxtester_core_mi.dll and dastudio.dll from quarantine to be able to successfully launch Simulink. Additionally, ensure your virus definitions are up to date.
As of December 2022, this false positive has been fixed by Avast.
