For which exact board are you compiling the project from the available targets? Which board do you have? When you follow the definitition of RED_LED from the main.cpp, what is it defined as?

You meant build_flags there?

can you upload the log of pio run -v -t debug? Because as seen here

          CXX="msp430-g++",

          ARFLAGS=["rc"],
          
          PIODEBUGFLAGS=["-O0", "-g3", "-ggdb", "-gdwarf-2"],
          
          SIZEPROGREGEXP=r"^(?:\.text|\.data|\.rodata|\.vectors)\s+([0-9]+).*",

          SIZECHECKCMD="$SIZETOOL -A -d $SOURCES",
          SIZEPRINTCMD='$SIZETOOL -B -d $SOURCES',
          
          UPLOADER="mspdebug",
          UPLOADERFLAGS=[
              "$UPLOAD_PROTOCOL",
              "--force-reset"
          ],

Flags should be -O0 -g3 -ggdb -gdwarf-2, not containing -Og. Have you updated all your platforms using pio platform update?
