Unterminated /* comment clang(unterminated_block_comment) error with red squiggle

[theMusicMan]

I am seeing a red squiggle in my code. Now, the code still needs development and is nowhere near completed, but it compiles and uploads to my M%Core5 fine, however I see a red squiggle on the first line of the code which when I hover over, gives this result.

I cannot see any unclosed /* lines in my code. Can anyone shed some light on why I am seeing this please?

Also, when I now add any blank lines at the top of my code, the code no longer compiles

Thanks
