Running transformation: System.Exception: Can't determine path of TSC.exe that is required to compile generated TypeScript files!

Hello,

I upgraded visual studio to version 2019.
Sometimes (not always) when transforming T4 templates I get this error. After the second attempt is builds sucessfully.
What could be the problem?
