Look at the output of dmesg. You may need to use sudo dmesg.

Look for something like OOM killed guile.
In that case you ran out of memory, too. That's kind unfortunate for 
time-machine to not work because of that, but I also sent you the package 
definition for musescore-3 with current guix. Try that approach.
