Operand type clash when use Always Encrypted

Question

When I connect SSMS to a SQL Server 2022 database with Always Encrypted enabled, I get the following error: "Msg 206, Level 16, State 2, Line 3 - Operand type clash: datetime is incompatible with uniqueidentifier."

This occurs with the code below:

DECLARE @Date AS DateTime = GETDATE(); 
DECLARE @Id AS uniqueidentifier; 

However, if I change the order of the declarations, the error disappears.
