I am new to all this stuff, but, I was building error free while trying to fix an issue with bed size and print size. I got it all working except z-axis is printing 2x higher than it should be, the test 20mm cube comes out 20x20x40. I made a change to configuration_adv.h file (I changed the Z_MICROSTEPS) and now it gives this error when building

I even went and used CTRL-Z to undo every change I made today to both configuration.h and configuration_adv.h. Both files are at the point where I had no issues with building, and it still cannot build anymore. I am not a developer, the only source I edit are those 2 files.
