Qubes os stoped moving or copy files from vm to vm

When i click move or copy nothing happens and on terminal i get “Request refused” when i try qvm-copy . But i previous had move files from vm to vm, now it stoped working. Thanks.

Your policy file is apparently broken.

It may be.

In 4.1 you should look in a number of places:
/etc/qubes/policy.d/90-default.policy - this is the default file.
If you have changed the default the recommended way is to create a new
file with lower number - e.g.
/etc/qubes/policy.d/30-user.policy - entries in this file will override
the default file.

There is also /etc/qubes-rpc/policy/, but the files there are
deprecated, and should not contain anything relating to copy/move.

If you have created a custom file check there - see if you are able to
copy/move between any qubes at all.
The policy file is provided by the qubes-core-dom0 package - you could
either extract the default file from that package or reinstall the
package.

I’m not sure, but the file looks good. The policy for move/copy is ask. But i have created a new 30-user.policy file with move/copy allow, it still not moving or coping files from vm to vm and i did not mentioned but the commands ctrl+shift+c and ctrl+shift+v also do not work, thanks for the help and the time.
