We will try to fix it. Stop the storagenode.
Restore the orders.db
from the backup (keep the backup for a while).
Open the orders.db
with a sqlite3 (you can install it or use the docker version).
sqlite3 orders.db
Apply this SQL script:
drop index idx_orders;
CREATE INDEX idx_orders ON unsent_order(satellite_id, serial_number);
.exit
Then try to start the storagenode
