Hello, I hope you’re doing well.  
I am using Quantum ESPRESSO within the Materials Square service  
I don’t understand this crash?  
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%  
task # 1  
from setup : error # 1  
too few bands  
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

You will need to increase the number of bands. Calculate the total number of bands from the total number of valence electron and add more to the bands to get good plot.
