Problem Upshifting

[California Longhorn 2021]

Recently my 2021 RAM 1500 with Hemi E-Tourque has not been upshifting from a stop after the auto start kicks in. It drives forward but does not upshift to a higher gear. So I go slow with high RPM until I can safely pull over and put the truck in Park. Then when I shift to drive it works fine. This has happened 3 times in the last month and it appears to be random.
Has anyone else had this issue? What was the fix?

Maybe an issue with the Gear Limiter/Button that is putting you into Manual Shift Mode??
