Chunks refuse to load no matter what i do

Hi!

Ive tried my best to not repost something allready existing but i couldnt really find something like the bug im experiencing.

No matter if its on a server or in singleplayer, since the 1.14 update i cant walk arround very far without ending up on the border of an unloaded chunk. I cant get it to load, and therefor either get stuck in it or even suffocate in it. I have a server with friends, they are absolutly fine and can walk arround freely. Here are some screenshots:

If the bug is allready solved, please link me to it, its really annoying and i have no idea what to do.
