The sources do not contain an accidental before the top note of the third on the 4th quaver in the bar, as a result of which it should be interpreted as e-g. It must be Chopin's inadvertence – the characteristic f(-d1) – e-g e-a sequence appears 10 times throughout the Prelude (excluding this place), always with g, even when it is preceded by a g-e sixth (in b. 41). Analogous sequences are to be found on a number of occasions also in other harmonic contexts, always with a minor third on the second quaver. Therefore, Chopin was fully entitled to consider the  to be obvious in this place.

The  restoring g in the 2nd half of the bar is absent in all the sources. It is one of Chopin's most common mistakes. The g note is so obvious that EE did not notice the mistake in spite of the cautionary  having been added before g1 in the 2nd R.H. chord.

On the 2nd beat of the bar in the R.H. we give the E minor triad (with a  before g2) according to FE (→EE2EE3) and Ap. The natural is, however, absent in FEcor and it was also not included in the copy which served as the base text for GE. In order to avoid the mode discrepancy between the parts of both hands, the reviser of GE1 took the decision to add a  raising g1 into g1 in the L.H. In GE2 and subsequent ones, an additional  was added before g2 in the R.H. These arbitrary changes were also introduced in EE4

In Ap there is no  returning a2 at the 9th semiquaver of the bar. It must have been Chopin's oversight.

In A there is no  returning f on the 9th semiquaver of the bar. It is almost certainly an oversight, corrected by Chopin in a proofreading of FE (→GE,EE).
