problem irreversible error with copy-paste

[feba]

Good morning to those who are connected,
I have a problem: during the command "copy" and "paste" from file to file comes out this message:

irreversible error: unhandled access violation reading 0x0042 exception at 12e98730h

Can you help me?

Thank you.
