I restored Windows to factory settings again, and when I logged back into Minecraft Preview—where I had left a world saved to the cloud—I found that the world had vanished; it had deleted itself and was no longer in the cloud or on the computer.

I might have found the main factor now, though I could be wrong. I had a different Microsoft account on my computer, so I created a new user profile—effectively a new setup—and removed the old account. Then, on the new account, I purchased and installed Minecraft Preview; the old account had stored an old world in the cloud for Minecraft Preview. While this was the first time I installed the game on the *new* account, it wasn't the first time on the computer itself, and that’s when the error occurred. I could be mistaken, but this is the most accurate information I have, and I’m fairly certain the bug can be reproduced.

A quick correction: the game isn't exactly being opened for the first time—I was already playing it. Before uninstalling, I had uploaded a world to the cloud and uninstalled Minecraft Preview; then I reinstalled it, and all this happened.

Before I encountered the issue, Minecraft Preview wasn't installed yet; I installed it and launched the game, which presented two options—directly from Windows settings or something similar—asking me to choose between using local storage or the cloud, and I selected the cloud. Basically, it’s a startup error that occurs when the game is opened for the first time; that might be what's happening.

My processor is an Intel iGPU, and in my case it's the same as, and sometimes worse than, OpenGL. The game stutters, the mobs lag, and even with fantastic graphics at 32 chunks, the FPS is between 30 and 5 with Vulkan selected, while OpenGL effortlessly reaches 60 FPS.
