Don't want to rely on strangers? You can create a custom Darkrise save file using a hex editor (like HxD) or a dedicated save editor.
Use the Darkrise Save Editor Tool (available on GitHub – search "DarkriseSaveEdit"). This GUI tool lets you slide stats, add items via ID, and auto-fix checksums.
If your local file is corrupted but your cloud save is intact, delete the game entirely, reinstall it, and log back into your cloud account to pull down the uncorrupted save file.
