Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.2-dev

Operating System (OS)

Linux

OS Version

Linux Mint 21.3 Cinnamon

Additional system information

linux kernel 5.15.0-157-generic

Printer

Bambu Lab A1

How to reproduce

Create a model which has 2 colours or materials on it.
Slice the file for 2 filament colours.
Export as gcode or gcode.3mf
Exported .gcode shows the model, but it can't be sent to the printer (the option is grayed out)
Exported .gcode.3mf shows the plate as empty.

Actual results

After slicing without errors, it exports to gcode.3mf or gcode, but gcode.3mf shows nothing on the plate and can't be sent to printer, and gcode shows the model properly, but the option to send to printer and print are grayed out as if the file/print has an error or is corrupted in some way.

Expected results

Above steps should create a functional gcode file, ready to print. The slice result shows no errors by itself.

Anything else?

sliced .gcode with grayed out send/print, no errors though.
