Error when using Simulink: "slCustomi​zer.static​Refresh" unrecognized field name "obj" on Mac

I started using Matlab R2021b + Simulink a couple of days ago on my Mac. I used it in multiple projects and it was working fine.

Now I am having some problems when using Simulink. When starting I get the following message in the Command Window combined with a refresh of my Simulink Menubar:

caught exception in slsvXtesterFEVALWithDeferredCtrlCHandling.

It happens nearly every time I try to do anything in a existing or blank model (I can't open the Modelsettings - they crash too). It's quite unusable this way.

I tried to reinstall Matlab + Simulink without success. I also tried:

restoredefaultpath

rehash toolboxcache

Which did not fix the problem. I tried to run:

sl_refesh_customizations

This resulted in a more specific error:

An error occurred during Simulink customization.

[...]

Caused by:

Error using slCustomizer.staticRefresh

Unrecognized field name "obj".

Does anyone have an idea on how to fix this problem?

Thanks

Hello,

This issue can be caused by a sporadic corruption of a file related to data dictionaries associated with libraries.

On your machine, please go to the MATLAB "prefdir" and then navigate into a directory called "SLLibraryLinkageData". This directory should contain a MAT file named "LibraryLinkageCache.mat". Please delete this file and restart MATLAB.

Deleting that file did not eliminate this error for me
