GPD Pocket 3 goes to sleep even though windows is set to never (screen doesn't wake up)

I have windows 11 set to NEVER go to sleep, turn off screen or any of that. Despite these settings however, my GPD Pocket 3 decides to sleep when on battery power. When I try to wake it up, the screen refuses to wake, forcing me to power off the unit and power it back on. I lose my work, I get angry. Can anyone offer any suggestions as to how I may rid myself of this frustration?
