Prusa slicer start G-code

[Bikeracer2020]

I really would like to use PrusaSlicer, however when I put the start and end G-code from my Qidi X-CF Pro in I get an error message when I try to slice with it and it will not slice the STL. All I get is invalid data

Start G-code.....
G28
G0 X{machine_width} Y5 Z50 F3600
M190 S{material_bed_temperature_layer_0}
M109 S{material_print_temperature_layer_0}
G92 E-19
G0 Y5 Z0.3 F3600
G1 X5 E0 F2400




End G-code....
M104 S0
M140 S0
;Retract the filament
G92 E0
G1 E-3 F300
G28
M84



Any help would be appreciated.
