Update on this one. Connected UART and I am showing an error of 80000140: APU Freeze (No Response) - GDDR6 Data Line Issue (Replace). Thermal camera showed RAM module 6 not lighting up. Reballed the module and reseated. No change. I then replaced the module with a known good. Still received no change. What makes up this data line besides the APU and the RAM?

Just an update on this one. This ended up being a bad APU. I re- balled and reseated the APU but it was too far gone.
