Problem runing asynchronous request!

[andraschris]

Visual studio 2022 C#

i have allready test the webserver via other routes

when i call until this point of code

GenRsp.Result = false; GenRsp.ErrorMessage = "test"; return GenRsp;
var response = await client.SendAsync(request);

i am getting result such us

when the code runs only this line
var response = await client.SendAsync(request);

some problem exists and i am getting nothing

is there a problem to run an asynchronous request ?
var response = await client.SendAsync(request);
