Compiling NVRTX caustics branch- Setup.bat errror

Any Visual Studio C++ experts here?
When compiling the NVRTX branch, running Setup.bat produces the following error. VS2022 installed with Windows 10SDK and required options. I successfully compiled an older branch about a year ago without any errors! Plenty of free space on install drives.
Unhandled exception. System.PlatformNotSupportedException: Thread abort is not supported on this platform.
