Take the SD card back to where you bought it and invoke warranty.
An embarrassing large percentage of 64GB SD cards have manufacturing defects.
So I recommend to not get another one either to replace this faulty one, but to get a 128GB card.

will it work if I go back to 4.3 android version?

No, because your Android version is not the cause of your problem. Bad Quality Control in the SD card's fab (in Taiwan, I think) is the cause.
