Self-built Bonobo.Git.Server Login Error: The required anti-forgery cookie "__RequestVerificationToken" is not present

I got the below error while logging in with admin/admin after first open the Bonobo server:

500 Server Error

A server error occurred when processing your request. Please try again or contact the system administrator.

Bonobo version: V6.5.0

Server: Windows Server 2016 Standard

And I have tried serial ways but no luck:

1. Add <httpCookies httpOnlyCookies="true" requireSSL="true"/> in web.config

2. Move the folder out of C:\inetpub\wwwroot;

3. Re-open the browser;

After googled hours in internet, it seems that the root reason is code issue. could anyone can help me out of this?

Below is the log copied from Bonobo.Git.Server\App_Data\Logs:
