Error detected in "launch auto "

Dear Experts,

I am not able to launch the p p > z h [QCD] process successfully. The terminal output is
included below for your kind reference.
Similar error occurs for many other processes involving " z h" in the final state. However,
there is no such problem while running p p > w h [QCD] process.

Please suggest a solution to this strange problem.

Thanks & Regards,

launch auto
INFO: Enter mode value: Go to the related mode
The following switches determine which operations are executed:
 1 Perturbative order of the calculation: order=LO
 2 Fixed order (no event generation and no MC@[N]LO matching): fixed_order=ON
 3 Shower the generated events: shower=OFF
 4 Decay particles with the MadSpin module: madspin=OFF
  Either type the switch number (1 to 4) to change its default setting,
  or set any switch explicitly (e.g. type 'order=LO' at the prompt)
  Type '0', 'auto', 'done' or just press enter when you are done.

Do you want to edit a card (press enter to bypass editing)?
  1 / param : param_card.dat
  2 / run : run_card.dat
  3 / FO_analyse : FO_analyse_card.dat
 you can also
   - enter the path to a valid card or banner.
   - use the 'set' command to modify a parameter directly.
     The set option works only for param_card and run_card.
     Type 'help set' for more information on this command.
