Hello Ata Arif

Is this happening for the same file / project on both computers? Are the files / projects you`re working on saved on a shared drive? If yes, please try to copy them locally on the PCs and see it it still crashes.  

Thank you,

Sorin

Now I saved a copy of the TM on the hard disk of my PC and cleared a new file without adding any TB and after two to three segments it crashed again same result 

I did same rusult 

now with an error message saying

Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
