After sometime in-game inside a world, the game freezes aswell most of my computer with it, and it keeps happening while Minecraft is open. My computer is a Samsung notebook with NVIDIA, Intel Core i5 8th Gen and 8GB of mémory. I don't know the real reasson of this since it seems to happen even with very little Tittle Tiles blocks in the world.

I highly recommend to update to the newest version and see if it still happens. Also make sure you have enough ram assigned to minecraft.

I will close this issue for now. If it still persists in the newest version use the debug mode (F3) and send me a screenshot of it.

In the screenshot above there's the result of the error, that usually is a game/computer freeze with or without the gray screen.
To try to solve this problem I instaled the mod FPSReducer which seemed to fix temporaly the issue, but when I remove the mod the problem comes back.

Now an error with the tape don't let me in my world:
