I've been stumped on this puzzle (at this spot mind you) for about 2 hours. I tried asking ChatGPT if it can identify any errors. It couldn't, and then I asked if it could identify my next logical solution based on where im at in the puzzle. IT COULDNT.

At this point I went to the answers in the back and checked if I screwed something up. I haven't yet.

Being that AI couldn't help me, I knew that reddit could.

Can someone please explain what im missing here. I've been an avid sudokuist for years and never been this stumped. Maybe im just blind and missing something obvious.

Please help before this puzzle starts affecting other parts of my life. My psyche is already starting to crumble
