File exception error SU 2021 Pro

Does this mean my file will not be saving when I click “Save”

How do I copy and paste all my gemetry into a new drawing (as a backup)?

Thanks!

Just rename the file and save it on your local disc.
What is the location of the current file?
It seems to be locked or hijacked by (anti)virus software.

That solved the problem.
Thanks Mike!
