And another thing i am planning to buy a new RTC, IC 23 and see if its the one causing issues.
By the way what temperature and air speed of Hot air gun shall i used to desolder the IC23 RTC IC.

If you are tired take a rest. Nobody forces you to work.
Then re-read #346. There are two pictures. On the first are the signals that you got from address line A0 and data D0.
Take the remaining 15 data signals and 17 addresses at the same scale and print out here.
You can do it in two steps. Today addresses, tomorrow data.
I understand that this is not easy.
But it needs to be done.

Could you do it correctly when replacing the CMOS battery.
That is, - having removed the battery (with the device turned off), short-circuit its seat with anything and wait for some time (10~30 sec), so that the transistors of the complementary pair (CMOS) finally lose their conductivity.

Yeah I indeed did that too..
