Would introducing some waits help?

When debugging at full speed it misses about 50% of the copy/paste process, pasting an empty range. I have tried clearing the clipboard before each copy/paste, but it's not helping. When debugging with breakpoints it never fails. Iterating over different files is not consistent and each time the copy/paste process fails in different elements. Have you come across this issue? Is there any workaround? Thanks, Juan.
