Usually when this message appears, the drawing file has been damaged beyond use. However, there are a few things that may get it to open:
-Try to open the drawing file directly instead of using the Recent
Documents menu.
-Check that the storage location that holds the drawing is working
properly.
-Use the RECOVER and RECOVERALL commands on the drawing.
-Attempt to insert the damaged file into a clean drawing or template using the INSERT command.
-Use an older or newer version of AutoCAD to try and open the file.
-Apply third party recover software Recovery Toolbox for DWG https://dwg.recoverytoolbox.com/
