Played it for a little while, got an error message and got kicked out, can’t get back in now and is forever stuck on the Mojang screen
This is on PS4 btw
Contact playstation support.
I don't think it is PS4-issue, but something of Mojang/Minecraft. See also https://www.minecraftforum.net/forums/support/legacy-console-support/3028119-im-stuck-in-the-mojang-screen
