No, 257 was a subvolume, (once upon a time named @) Your *Default*
subvolume, the subvolume as the root of your device, should be 5

I don't even... you were supposed to rename subvolume @ not try to move
a mount point into a subdirectory of itself
I don't know what this command did to the underlying file system.

You'll notice that @home is missing from this list. We aren't looking
at the same top level directory anymore. Possibly an effect of having
some weird default subvolume now.
I'm not at all sure what's the best way for you to untangle this knot
