The same issue here. The launcher works, but when you launch Minecraft Bedrock, you get the red Mojang screen for a few seconds, then it all closes. Tried a fresh install, tried repairing it too. Can this be patched urgently?
Having the same issue, since this week.
Have exactly the same issue. When I try to launch Bedrock version on the PC, I see the red mojang screen, then it shuts down.
Mine does exactly what yours does, in your last video. Mojang screen comes up and then disappears.
