Invisible barriers forming in the middle of my Minecraft world

Was breeding horses then wandered off for a little while to look for another horse to breed. Everything was going completely normally up until this point. I was bringing the horse back when all of a sudden there seemed to be an invisible barrier I could not get past. Two wild pigs walked into this strange invisible barrier that wasn't supposed to be there and their bodies were locked in place, but heads were spazzing out the whole time. Any blocks around this barrier that would normally be mineable (trees, dirt, grass, etc) were not. Exiting and coming back to the world did not fix the issue, and the problem was still there even in an entirely new world. There are so many constant invisible barriers blocking me that the game is definitely unplayable for me right now.
