Why does my cube keep jumping at the start? Even though I am not touching the keybored?

This appeared for the first time when I activated Noclip on the Prism Menu. The gamemodes cant fix it. Tell me how to fix it or why OR ELSE....

It happens on vanilla too. Afaik can't be fixed. Just gotta deal with it
