I ask for help here because I think it is the right place because it must be a failure of some script:
I update gameguru max and the launcher stayed 2 days without advancing the download, when everything had already been downloaded. Said there were still files to download (fix launcher. Because it has a lot of bugs). Then I went into gameguru max and the player's gravity changed, when he walks he makes little stumbles and when he jumps he keeps walking towards the sky and it's horrible, not just gravity changes, movement and everything. I tried to put more gravity or something but it gets worse, it cannot be fixed, I seek help from someone who knows how to fix it or what is the error? to gameguru and gameguru plus (that is, both) the same thing happens when walking. here is an example video:
