Josephine Thanks, maybe I should stop worrying about it.
On the one hand, yes, you should stop worrying about 😃 it sounds lovely!
On the other hand, if you are worrying about it, and you experience inconsistency (i.e., when you play the piece all the way through, sometimes it's ok and sometimes it's not), then it makes sense to work on it.
You've gotten lots of advice about how to play it, perhaps I can give you some advice about how to practice it. By which I mean, general practice techniques that can be applied to any music where you have a sticky point, not just this piece and this measure.
(Note, when I say "sticky part" below, I mean the part that's giving you trouble, as well as a little bit before and after it, so that you're linking it to the rest of the piece.)
Make the sticky part the very first and very last thing you play in every practice session. Before you do anything else, when you sit down to practice, play this part in isolation. First slowly, then at tempo. Then, at the end of the practice session, play this part again, first at tempo and then slowly. Make it be the last thing you do at the piano for the day.
Before you play the whole piece through, practice "dropping in" at various spots before the sticky part, and then play through the sticky part through to 1-2 measures after it.
When you decide that you're going to "play through," always play all the way through, no stopping, regardless of whether you flub up on the sticky part.
Look for hidden trouble spots before the sticky part, because it may be that the sticky part goes well when you sail through the part four measures earlier, and the sticky part trips you up when you're distracted at that spot four measures ahead.
Figure out what helps you play the sticky part well. For example, maybe counting silently (in your head)? Saying the note name silently? There must be some tricky that let's you zero in, really focus your concentration and play through the sticky without flubbing. Find that trick, and then practice doing it when you play through.
Before every play-through, remind yourself that 1) you know how to play the sticky part, and 2) in the end, it doesn't matter whether you play it right or not, because no one else will notice a mistake there nearly as much as you do. Then, believe in yourself, and enjoy the play-through.
These should help! I am going to start employing them on a piece I'm working on right now as well.
