I think this usually happens when something else is using the drive. You'll have to find out what else is using F:.

Yes! I have figured it out about an hour ago and came here to update you.
After terminate a lot of background processes, I suspect that ABService.exe (Aomei Backupper) or another storage related software like VeraCrypt or Montainduck was causing the issue.
Thank you for reply!
Great! Possibly we need a better error message then, "access denied" isn't all that helpful.
FWIW if you end up here after running into this problem like me, I used LockHunter on the drive to see which processes where locking, pressed the 'Unlock It!' button and then I could execute the conversion command successfully.
