Trouble moving when I first enter my world

When I first enter my world and it starts to load the surrounding areas, I cannot move, even though I am pressing the keys, it moves, but after I press the key, the same thing happens when I walk to other more remote areas of my house and also the same is true in the nether.

This did not happen to me in version 1.14, when I just updated it, it entered my world and I passed that error / bug.

Sorry for my bad English, i used a translator.
