Anypoint Studio Missing Features After Installing Anypoint Enterprise Security Packages

CAUSE

The Anypoint Enterprise Security (AES) plugin is not supported in Mule 4.  AES is for Mule 3 but Studio 7.X uses Mule 4.

SOLUTION

The Anypoint Enterprise Security module was split into different modules in Mule 4, which are specified in this documentation article: https://docs.mulesoft.com/mule-runtime/4.3/migration-aes. You will need to migrate the Anypoint Enterprise Security features to Mule 4 modules.

Depending on your required use case, replace your AES functionality using the new modules introduced in Mule 4 as explained in the above article.
