Last message is in Norwegian and says permission denied because the file is in use by a different process.

Pressing Save again works. If you renamed several files it will fail once for each file. e.g renaming 10 files causes save to fail 10 times and work on the 11th time.

Merging files causes similar issues. If you merge 4 files into 1 save will fail 3 times and work on the 4th. This makes me think that rename is implemented by deleting the old file and saving a new file and in both save and rename cases file is deleted before it is closed and that this isn't allowed by windows

I cannot replicate with that set of steps on my windows machine. Note
that the editor operates on a copy of the original book folder. Every
operation is performed on the copy. When you click save the original
folder is updated from the copy. SSo there is no question of calibre
deleting still open files.

The only suggestion I have is that you exclude whatever folder you are
using for the books from your antivirus/file sync type programs as these
can often hold a file open.
