T4 Template File doesn't compile VS2019 V16.4.5

I have a T4 Template file in my project and I use it everyday but after upgrade into 16.4.5 version I'm getting this error when I Run Custom Code:

I tested the same file in my colleague's workstation with previous version of VS and it worked.

just exclude all project files and folders then include them again! it works
