Teamcity fails to fetch files from Azure Devops - azure-devops

Question

I am very new to the TeamCity and want to learn auto build and deploy applications from online TFS. My project has windows and web apps developed in .NET only.
I have no code on my machine and directly using online TFS as source.
VCS Root setting works fine and connection gets successful.
In the Build Step, I am using Build as the first step using MSBuild. When I click on RUN it starts the process and shows the first step as UPDATING SOURCES. In the code checkout directory, it creates only directories and there is no even single source code file though I can see all code files in TFS online. After this step it shows error:
Failed to start MSBuild.exe. Failed to find project file at path:
C:\TeamCity\buildAgent\work\740b9db587af8795\ProjectName.sln
ProjectName.sln file exists in TFS at https://ProjectName.visualstudio.com/DefaultCollection/$/Main/MainBranch
I am not getting what things I am missing. I googled much about but I wasn't able to get what is missing here. What extra steps I need to do to get this working.
Appreciate your help.
FI: Teamcity Version 2018.1.3 (build 58658). Teamcity server and build agent are on the same machine: Win 10.
Edited:
Below is screenshot with the RUN process.

Answer 1

Finally got the issue issue resolved!
The token generated for the TFVC access was not having sufficient permissions. Changed the access token to have Full Access and it started working and I can see all code files in the checkout directory. Thanks jesse for your comments.
