Tool/software:
I seem to have lost my option to build or debug. those useful options are stricken from the context menus. Ctrl-B excites the strobing blue bar, but nothing else -- nothing in the build output. The F1 CCS:Build option? Nothing ...
If done 'things' to try to repair -- some rational, some superstitious. I've now wasted over 2 hours. My teammates are laughing at me.
Below, enjoy my rendering of the situation. No Build options. Debug option Greyed out.
