Why is the IRS rejecting my return for AGI mismatch when I am entering the precise number from my previous year return?

I entered my AGI from box 11 of my 2022 tax return, the IRS rejected my 2023 return citing a mismatch between the AGI I entered and what they have on file. I confirmed my AGI with a return transcript supplied by the IRS as well as the digital copy 2022 of my return at the time of filing.
