kicadstepup freeze freecad when Maker Workbench installed

[lumostor]

Hi, there is an issue with kicadstepup when makerworkbench is installed. In that condition kicadstepup is very long to load a kicad board ( many minutes) then crash or just freeze.

I removed Maker Workbench, after that, kicadstepup loads boards normally.

I'm using FreeCAD 0.22dev (37668 git), with kicadstepup 12.2.3. I didn't check Maker Workbench version before removing it but I was (and still) up to date with every external workbench.
