3D printer brand / version + firmware version (if known)

Ender 3 V2 + bltouch ( merlin 2.0.1 i guess)

Behavior

*Crash when using 0.25 nozzle
**This only apply to the version 2.3.0 as LATEST STABLE , this does not occur in the RC3 version ( where this report is based on )

Project File (.3MF) where problem occurs

prusaerror.zip

*This file also include my printer profile , exported from verion 2.3.0 and imported in the RC3 version
this can be repeated by just using the import config and then the program will crash with that file , STL file also included ( as i use STL instead AMF

I can reproduce crash when importing PrusaSlicer_config_bundle-0.25.ini using "Import Config..." option (Import Config Bundle... works).

Fixed with 5294a48

Importing a config bundle as a config file was broken for
multi material FDM printers, where a different filament was active
for each extruder.

Thanks for the report.
