Recover Encrypted and Account Restricted .json

Hey,
a few days ago the the computer i used to host Vaultwarden on broke.
The hard drive is dead as well.
Of course i have a backup. 321 rule am i right?

This however, is where i messed up, as i must have used the “Account Restricted” option during the export.
When trying to import the backup into another Vaultwarden i get “encryption key does not match the encryption key used to export the data”
I also tried BitwardenDecrypt from github, which threw the error “No Accounts found in data.json”

I am somewhat at my (to be fair quite limited) wits end.
Does anyone know something i could do to get my passwords back?

The motherboard is still working for some reason, and if the encryptiion key is made up of name/email password and mac adress, there should be a way right?

Thanks and have a great day

Not sure how you created the backup, but i guess you used the encrypted export option linked to the account, and not with a password.

In that case you need to exact same account including keys which are stored in the database.

Without those you will be unable to decrypt the backup.
If you have a backup of your server data somewhere, that would help. Otherwise you’re out of luck.
