I have no idea why this is happening because last time I was able to move and jump when testing, but now somehow it doesn't work anymore. My output has nothing wrong and the scripts have nothing wrong too, plus I checked it a couple times, but have no clue still.
Check the WalkSpeed property on the humanoid. Is it above 0? Is your PrimaryPart/HumanoidRootPart anchored? If so, unanchor it. Does walking around in a new place work?
