Start by reproducing the crash through the Import dropdown's 3D model action using the reported SEToolbox and Space Engineers versions. Review the attached Report.zip and Windows event log, especially the atiumd64.dll access violation, then trace the 3D model window startup. Done means the window loads without crashing in the reported scenario or the incompatibility is clearly identified.
