WP Migration .wpress Backup Recovery

Recover corrupted/truncated All-in-One WP Migration .wpress backup

I need someone experienced with All-in-One WP Migration .wpress backups to recover a corrupted or truncated backup file.

Context:

WordPress site backup created with All-in-One WP Migration
An older backup from April 2025 restores correctly
The latest September 2025 backup fails on both GoDaddy and Hostinger
All-in-One WP Migration fails during “Unpacking configuration”
PHP error:
realpath(): Argument #1 ($path) must not contain any null bytes
Official ServMask Traktor also fails with:
“Failed to read file header. The backup file might be corrupted or truncated.”

I do not need a redesign or a new website.

I need you to:

analyze the .wpress file
recover as much data as possible
ideally repair/rebuild the archive so it can be restored
otherwise extract the database, uploads, theme, plugins and other recoverable files

Please only bid if you have actual experience recovering corrupted .wpress archives.
