Simulink and simscape used to work fine, until yesterday it started giving me an error:

Caught "std::exception" Exception message is:

Failed to load bundle #444: C:\Program Files\MATLAB\R2022b\bin\win64\dastudio.dll

I tried uninstalling and reinstallilng matlab, i tried deleting dastudio.dll then readding it, yet nothing worked.

What should i do to fix this error?

Thanks

Same, also the antivirus blocked the file

The file: MATLAB\R2022b\bin\win64\dastudio.dlll must be added to the antivirus exceptions. It works perfect!!!

Apparently this error was due to a false positive quarintine from Avast Anti Virus, or another anti virus software.

In orderto fix this problem, open your anti virus software and remove the corresponding .dll file from the quarantine list and run simulink again. No need to uninstall and reinstall Matlab.

In my case, for some reason the antivirus cannot restore the file, it is necesary to uninnstall and reinstall after desactivating the antivirus

Hi everyone,

We are aware of this issue at MathWorks Support. It may be caused by Avast & AVG antivirus software putting "libmwxtester_core_mi.dll" and/or "dastudio.dll" in quarantine. It is safe to assume that this is a false positive. See the following post for more info:

HTH, Stefanie

I solved this issue by disabling AVG, fully uninstalling MATLAB (making sure to delete all remaining files from Program Files), then re-installing MATLAB while AVG was still disabled. Simulink now works!
