Frigidaire Ice Maker Issue

Maybe someone out there had an idea of what's going on. I have a Frigidaire FRFC2323AS5 French Door fridge (Home Depot). Ice maker is upper-mount in the fridge section with door dispenser for water and ice. The ice maker has not worked since new (mid-May 2024). Water is not making it to the ice maker, but will dispense in diagnostic mode. Water filter is freezing which then.stops water altogether. The air tower has been replaced twice, many filter replacements, and just replaced water inlet valve. Still not producing ice. If I do dispense water in the ice tray via the diagnostic mode, the tray will not empty at all, just sit there with ice cubes in it. If I empty the tray via diagnostic mode the tray never fills with water. Water pressure in line to fridge is fine.
