I know how to fix black screen by disabling and reopening the permission to show pop-up
@GNaFF can u fix it
it's like when you enter the game for the first time and exit and then re-enter it will go black screen
2nd advice is to buy event artifact and upgrade to high then sell it for more materials.
Important note : when upgrading Astro Head Start not more than 100% very high ban rate

If you dosn´t activate Artifact Upgrade, you can use Library
