MCD / MCD-6260

When I click on play, the game starts normally, we see Mojang studio, unreal engine, etc ...

The game starts normally but when I click when I am told "click on any button", the game starts to load a little then displays a small empty white pop up in the middle of the screen with only one cross to close it and when I close this pop up the game starts to load indefinitely with the small block of redstone at the bottom.

I let it run for 2 hours but absolutely nothing is moving

Thanks in advance for helping me sort this out

Have a good day
