in AWT - FormDesigner() -> .initLookup() -> PaletteUtils.getPaletteLokup() -> FOQ.getOwner()
where FOQ is being blocked by a concurrent project open. Unfortunately there is nothing we can do about it on project side
please evaluate if there is a chance to invoke the call outside of awt
feel free to close otherwise
thanks
