Does it feel or sound like it even tries such as clicks when it rolls? If you hear clicks it could be the pawl is not entering the notch in the gear possibly caused by something bent or worn.
If there is no sound or attempt at all to engage it could be the assy on the manual shaft that pushes the pawl up into position to enter the park gear has issues. A broken roll pin or spring could be letting the shaft rotate without moving the assy or issues with a different pin could have let the roller that actually pushes against the pawl move out of position so the pawl is not going up high enough to engage the notch. There is a pin behind the engagement assy to keep it upright and not go past vertical so as to keep the pawl fully engaged. If that pin has broken it could be allowing the mechanism to go too far and let the pawl drop down out of the parking gear after it was engaged. All have been reported by others.
To check any of those items will require draining the fluid and removing the pan. The condition of the engagement mechanism and manual valve lever will be easy to see. Most of the pawl will not be visible enough to see much of anything without further disassembly
