This should work. Could you try to add "--pbkdf pbkdf2" for luksAddKey?

This will use old PBKDF2 (as in LUKS1) for keyslots.

If it works, I strongly suspect you have issues with hardware.
Specifically if you say "sometimes it works" - this must work always,
it is a deterministic algorithm.

I have seen this several times (note new keyslot use a lot of more memory
that could trigger the issue).
