IDE damaged? Red lines and thousands of lines of gibberish



My IDE for my Harvard CS50 course is apparently damaged. There are thousands of lines of meaningless text with redlines running through them. I cannot view any of my work or make any programs.

Any idea of how to fix this, so I can get back to class? What could have caused this?



It appears as though I’ve opened the compiled binary editor rather than the source code.

Double-click the FILENAME.c file on the left, not the program file.
