Can't rebuild Cubecell example sketch Factory Test

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.

C:\Users\user\AppData\Local\Arduino15\packages\CubeCell\tools\gcc-arm-none-eabi\8-2019-q3/bin/arm-none-eabi-objcopy: supported targets: elf32-littlearm elf32-bigarm elf32-little elf32-big plugin srec symbolsrec verilog tekhex binary ihex

Apparently something is not right in a path or directory.

I found the issue! My local sketch ino had SPACEs embedded in the file name.

Apparently arm-none-eabi-objcopy doesn’t like embedded spaces. The problem may lie in the wrapper, CubeCellelfTool.exe which invokes objcopy.
