Autoplant/Autocad drawing file stuck at the point “At_start_doevents” while opening

Dear Bentley Family,

When we open any multiple (second/third) autocad drawing , its stuck at the point “At_start_doevents” as shown in the attached pdf-screesnshot. Its not going further . Due to this we are not able to open multiple drawing.

Please let me know any solution and why its stuck at this point .

 Waiting for your earliest reply.
