EF Core migrations timestamp without time zone field to timestamp with time zone

[esersahin]

PostgreSql version 13.1 on debian operating system.
PgSql version is Npgsql.EntityFrameworkCore.PostgreSQL 6.0.0
My operating system is Macos

public class TimeStampDemo
{
public int Id { get; set; }

[Column(TypeName ="timestamp with time zone")]
public DateTime Ts { get; set; }

[Column(TypeName ="timestamp with time zone")]
public DateTime TsTz { get; set; }

}

When I want to change the ts column type in the TimeStampDemo table from timestamp without timezone to timestamp with timezone with ef migration, I get the following error.

dotnet ef database update command after getting this error.

What could be the cause of this error?
