Big Sur iCloud Unsupported Device.

[bbeach12]

I'm new to this thing. I followed a tutorial and installed Big Sur and it runs fine and its responsive. However, whenever I try to sign into my apple account it says ICLOUD_UNSUPPORTED_DEVICE. I'm assuming there's a way to fix this issue bit i have no idea where to begin. any and all help would be appreciated.
