I can reproduce with the TeknoParrot.Collection.2026-02-19_RomVault.zip version.

This is the problem: NaturalIntelligence/fast-xml-parser#789

Rather than behave like every other DAT group out there and split their catalog into multiple DAT files, TeknoParrot decided to put absolutely everything into one DAT file. The resulting 605.9MiB file is unusably large.
