I installed some extensions from warehouse. All was fine until I installed some light extension and sketchup crashed.
I uninstalled and reinstalled sketchup, erase all the extensions from “extension warehouse- my extensions”
But now it still says “extension warning” and crashes when i dry to open it.
What extension exactly? and what version are you using? Your profile says SketchUp for schools but that’s an online version for little schoolchildren and has no abillity to use extensions…
