Error
Please configure CAD interface in Reader mode
"System.TypeInitializationException: The type initializer for 'Ansys.UI.Toolkit.Application' threw an exception. ---> System.ArgumentNullException: Value cannot be null." It appears you did not provide any path for CAD installation which is required for plugin mode.

if still running into errors, then please check OS version
cat /etc/*release
which should show the exact patch level of CentOS 8 in use. please check if the patch level is supported in platform support document "https://www.ansys.com/content/dam/it-solutions/platform-support/ansys-platform-support-strategy-plans-sept-2021.pdf"
