bad file descriptor
I am a teacher and desperately need musescore to teach in these remote teaching times ...Each time my students send me a mscz. file the graphic for a new version appears briefly when I try and open these files ) grey with a more slender font) and then a prompt tells me to update which I have tried to do countless times ...the blue icon that I press to get access tells me that I have the current version ..but clearly I don't..a further prompt says I have a bad file descriptor. any help ??
The first attached file will not open and causes the "bad file descriptor " message.....
The second file was created with the new version which somehow was able to be downloaded...it looks different to the blue shortcut.
