The first step in any forensics challenge is to verify the file type and examine basic metadata. 2022-06-03 11-32-03~2.png
After repairing the height or running StegSolve on the "Gray Bits" or "Red 0" planes, a text string (the flag) typically appears at the bottom of the image or in a separate output window. It usually follows the format CTF{...} or FLAG{...} . : Locate the IHDR section (usually starts at offset 0x0C )
