The note should be played as E sharp. What happens is that there is a change in the key at this measure. The key changes from C sharp minor to D sharp major.
D sharp major is an unusual key, with key signature F# C# G# D# A# E# B# F## C##. The double sharp F and C appear several times in measures 18, 19 and 20. The E is sharp, not double sharp.
The manuscript probably had an E sharp, which was then edited as E double sharp. E sharp makes sense musically, in the key of D sharp major, and appears later one octave higher in the same measure.
It is not a coincidence that many interpreters play this note as E sharp. It makes sense musically, it is plausible that the sharp in the manuscript could be carried on edited as double sharp, and it aggress with the major, contrasting key in the measure.
I have added a video with another example. This video has a visual feature that might be helpful.
