Solution by SenorGPT:
Used x64dbg to analyze the main function, bypass a simple IsDebuggerPresent anti-debug check, and follow the calls that read, encode, and compare the user input. The program converts each character to a \xHH form using the format string "\\x%02X" and compares against a stored constant, revealing the correct password.
