Background:
That Android Bitwarden build had a bug (issue #6293): the exported file could not be imported elsewhere—even with the correct password, import reported an error.

My situation:
My self-hosted Vaultwarden server is no longer available. The backup JSON was exported with that app version, and I cannot import it successfully now.

Question:
Is there any way to recover this backup JSON or decrypt its contents?

I have solved this problem by writing a Python script to decrypt the incorrect format JSON. Thank you very much for your attention.
