There is a newer version: 1.12.1

Why is this an issue?

  The argument passed to FreeAndNil must be an instance of a TObject descendant.


  Prior to Delphi 10.4, the signature for FreeAndNil is untyped. This erroneously
  loose contract allows any variable to be passed into FreeAndNil, which will cause
  a runtime exception.

How to fix it

  Remove the incorrect call to FreeAndNil - non-object types are either managed or
  have an alternative way of freeing associated memory.
