Thanks for the feedback. I am interested in how this problem is
resolved so I plan to follow this bug.

What I don't understand is that if vim cannot save the file in
encrypted form becuase the key has expired (and goes not to delete the
file's contents), why is it able to decrypt and open it in the first
place? If it at least did not open the file, it would prevent the data
loss.

Warm regards.
