Same issue here using version 1.16.21 on Nintendo Switch using a child account.
Error box that just says “An Error occurred” and then a pop up that says “level export failed”, does this repeatedly with no sign that the world seed is even uploaded.
Can access the realm using the Switch or Windows 10.
Unable to archive and re-download per advice from [Mojang] CornerHard as using physical game cartridge.
