Few "Invalid" main stat in artifacts

[starrynte]

Describe the bug

1. I scanned 984 artifacts, 5 of them had "Invalid" main stat in the ScannedData/artifacts json. All the "Invalid" artifacts were Clam pieces, 4 were HP% and 1 was DEF%.
2. Trying to export to GOOD with "Invalid" main stat causes a crash. Was able to work around by manually fixing the "Invalid" pieces and restarting.

System.Collections.Generic.KeyNotFoundException: The given key 'Invalid' was not present in the dictionary.

Expected behavior
No "Invalid" scans / app shouldn't crash when exporting

Screenshots
Couple of the problematic pieces

Additional context
Didn't see any errors in the log

I did have Windows night light on, maybe that could have affected the scan?

I am currently working on improving accuracy and reducing CPU usage of the weapons/artifacts scan. I do notice sometimes the scanner gives incorrect results, but mostly on substats/equipped characters and never on the main stats. Thanks for letting me know and I will look into it.
