The Modrinth listing for 1.3.2-beta+fabric.1.20.6 specifies the compatibility range as 1.20.2-1.20.6. However, because it was compiled against Java 21 it cannot be run on 1.20.2-1.20.4 instances which use Java 17.
This can be fixed on the user-side by modifying the instance to use Java 21, but in my opinion that should not be required.
