Apply commands RECOVER, RECOVERALL in AutoCAD. Moreover try to open .dwg file in other versions of AutoCAD, if this method doesn't help you, then you may use DWG Repair Toolbox. Software is used only in cases, then usual solutions don't work, it is accessible on https://www.repairtoolbox.com/autocadrepair.html
