Fix: Phantom Blade Zero (and any Unreal game laid out like it) crashed with DLSS 5.
The game ships its own DLSS, but its folder layout put the Engine\Plugins tree two folders above the exe, where the scan did not look. The app set it up as a game with no DLSS and ran the Feeder, which created a second DLSS feature next to the game's own and crashed inside it. The scan now also checks Engine\Plugins up to three folders above the exe, so the game gets the "game has its own DLSS" setup. Tested in game: runs without a crash.
If you installed on a game like this and it crashed, remove the old setup in the app and install again.
