Should one change the direction of the Qiblah during prayer upon remembering its incorrectness?

If a worshiper exerts their effort in discerning the Qibla through ijtihad (independent reasoning) or taqlid (following a qualified scholar), and then realizes their error during the prayer, they should turn towards the Qibla, and their prayer remains valid. They should continue their prayer based on what has already transpired, as there is no obligation to repeat the prayer if the error becomes apparent after its completion.
