I had the same problem. I was trying to launch QT program using systemctl service. For me the solution was to make service launch the .sh file that exports necessary variables from QT project Build Environment and after that launches my program.
So it might help in your case too: you might missing some environmental variables if the program launches normally from command prompt but your service can’t launch it.
