The reset worked like a charm.
After another four attempts, the backup finally worked.
Had to turn off the experimental storage backup, which were basically just photos.
Thx!
Found a tiny description of how to reset the SeedVault app here: https://discuss.grapheneos.org/d/18003-seedvault-reset/4
"To reset seedvault search in Settings for seedvault then goto storage and clear storage."
Will give it a try today.
