Musescore 2 and Musescore 3 can't read the converted file
This morning, I converted a pdf file in muse file easily. But I can not open the file neither with Musescore2 (error, install musescore 3) nor with Musescore 3 which crashes (does not stop working and I have to force him to leave).
So I tried to open old musescore files, it seems to work.
I tried to request the conversion of an old file that worked and there, it is planted in queue with refresh every 3 seconds.
And last thing, I can not send mail to Musescore support (firstname.lastname@example.org) because they are considered spam
