Error when using Simulink: "slCustomi​​zer.stati​c​Refresh" An error occurred during Simulink customization

I started using Matlab R2021b + Simulink a couple of days ago on my Windows 10 OS. 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.

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

Thanks

It got fixed by doing a clean reinstallation.
