I am able to compile and upload the CubeCell example Factory_Test_AB02 from the Arduino File menu. But when I create a new sketch and copy the ino text, and compile, it fails to build the hex file. Here is the error message. I am using Arduino IDE 2.0.0-rc9.4 on Windows 10.

Apparently something is not right in a path or directory.
