I don't see any info regarding a crash, but you do seem to lack permissions to open the COM6 port.

To me it looks very similar to this issue that we had back in 3.4: https://github.com/Ultimaker/Cura/issues/4016

Could you check the workarounds that we posted there?

Which version of Cura are you using?

Edit: Nevermind, I can see that from the log: 4.0.0.

Latest version

Could you go into the preferences and disable the "Send (anonymous) print information" preference there, and then try again? If it doesn't crash then, that confirms that the bug in #4016 is back.

Thanks for the respond... IS WORKING.

I can confirm that print on usb and save gcode after Send (anonymous) print information disabled

Please let me know if you need any log.

Thanks again all of you for the help.
