CRITICAL FIX: Resolve StackOverflow in debug function

Browse Source 
Fixed infinite recursion in customDebugPrint function:
- Line 15 was calling customDebugPrint(message) instead of print(message)
- This caused stack overflow crash on any debug output
- Now correctly calls print(message) to avoid recursion

The app was completely broken due to this recursive function bug.
Debug output now works correctly without crashing.
