For anyone interested, I wrote a quick script to convert the Enpass 6 JSON export into a CSV. I looked at Safe-in-Cloud but preferred something I can run locally (you just need Node.js)
https://github.com/migvill/enpass-to-csv
I only read in the basic logins, I don't use Enpass for creditcards, etc so I haven't tested for that. It's not perfect but I was able to successfully use it to migrate to Lastpass since V6 is too buggy
I might come back if it gets better again
Cheers
