The mixer on Musescore stays open after I clicked on it, shortly after I downloaded the new update.

Hi, could somebody help me please. I openend the miwer on Musescore while writing and now I can't get it to go away. It is blocking my view of the score and also some of the tools.

I have restarted my computer several times and restarted musescore several times. However, with every score i open it is still there.

Anybody have any idea how I can get it to go away?
