I tried to run ANSYS workbench 2024 Student version but it is giving "An unexpected error has occurred: The type initializer for 'Ansys.Core.Expressions.ExpressionEvaluator' threw an exception." error.
Upon further details it says following

An unexpected error has occurred: The type initializer for 'Ansys.Core.Expressions.ExpressionEvaluator' threw an exception.

Hi,

What's the release no? Can you rename the Ansys folder (%appadat%) to Ansys.old and try again?

try reinstalling ANSYS and ensure required .NET frameworks are correctly installed.
