Is that this app particularly designed for pubg, or am I ready to make use of it for different apks?

Downloaded a gfxtool to try to assist upscale a few of my older android video games, however i maintain working into this error when establishing the app. I by no means even acquired to a display screen the place I’ve an opportunity to pick a sport or app.

Primarily based on what I discovered, it appears my app is making an attempt to launch PUBG? The app on the playstore by no means talked about this being a sport particular launcher so I’m feeling a bit confused. How am I capable of open different video games via the app?
