Cursor never focuses when fastload is installed

[Cartrigger]

Fastload (a very nice worldgen optimization mod) when loaded with Nvidium and make a Singleplayer world, the cursor never focuses and thus you cannot play the game.

Windows 11 Pro MC 1.20.1

This is a known issue of FastLoad. Just don't use it. If you want faster world load, use ModernFix instead
