So been doing some additional testing... I turned off my power supply and I unplugged everything, the USB plug, commander pro, and unseated the LCD. Starting working for 3 cold boots. Then while watching a YouTube video the LCD went to exclamation mark again. So I tried this time just cutting the power to my power supply again by flicking the switch on the power supply. LCD starting working again and saw hardware screen, and setup screen options in ICUE. Within 10 minutes back to exclamation mark again and no screen option in ICUE.
I tried rebooting again and now the LCD is frozen on 35C, no animation nor change.
I am 100% convinced this is a software issue.
