after I change the workspace from " Drafting & Annotation" to " 3D Modeling" , a fatal error occured immediately and the file closed.
I opened the flie again and clicked on "recover" pop-up window. Then another window appeared asking for fixing the problems of the file, clicked " fix" , a window apperaed saying that 5 errors were found and fixed. However, it didn't last long till the error happened and the file closed. Since that time I tried many times to open the same file, older files , the software itself .. once the welcom window appears the software closed Immediately!!
the software closed very quick , I could only read "AutoCAD cannot continue" on the error pop-up window, but found the below at the "acad" notepad file:
" FATAL ERROR: Unhandled e0434352h Exception at 75c3d3cfh
