JWT token authentication not working When upgrading .net 5.0 to .net 6.0

I have converted .net 5.0 Web API to .net 6.0 Web API.The JWT Authorization was working fine in 5.0.When I change "startup.cs" to "program.cs" then I am getting "Unauthorized" error. Please check below code for "program.cs" and advise where it is problem.

Note:-

all API working fine without authorize
