Can't open Simulink Model: "state not recoverable" error

Hey everyone,

after restarting Matlab I am getting the following error when trying to open a Simulink model:

Caught "std::exception" Exception message is:
Loading C:\Program Files\MATLAB\R2021b\bin\win64\simulink_plugins\record_playback\libmwstreamout_blocks_reg.dllfailed with error: Die angegebene Prozedur wurde nicht gefunden.
: state not recoverable: state not recoverable
Caught "std::exception" Exception message is:
Loading C:\Program Files\MATLAB\R2021b\bin\win64\builtins\shared_sdi\mwshared_sdi_mcos_builtinimpl.dllfailed with error: Die angegebene Prozedur wurde nicht gefunden.
: state not recoverable: state not recoverable

The text after "failed with error" translates to: "The specified procedure was not found."

As the error seems to be a corrupted Matlab install, is there a way around a complete re-install?

How can I prevent this happening in the future?

A bit more information on what lead to the error:

• Deleted a manually defined data type for monitoring activity of a Stateflow State Chart from data dictionary of Simulink Model
• Model unexpectedly still works fine, no compilation errors
• Closed the Simulink model
• Closed Matlab
• Opened Matlab
• Opened Matlab Project
• Opening the Simulink model fails

Thanks in advance!

I understand that you are trying to find a way to completely re-install MATLAB as you are assuming the errors are related to corrupted installation of MATLAB. Please try the below troubleshooting steps.

• Uninstall MATLAB.
• Remove all MATLAB Installation folders.
• Remove all Preferences and temporary files related to MATLAB.
• Restart your computer.
• Re-install MATLAB.
• Please refer to this link for more information: https://www.mathworks.com/help/install/ug/uninstall-mathworks-products.html

Now check with the same model whether you are getting any errors.

Hope it helps to resolve your query.
