i want to mount/format

You cannot mount a partition w/o filesystem and you cannot format (mkfs) a partition w/ a mounted filesystem
Post the output of

lsblk -f

and specify what you actually want to do with what partition.

Can you

udisksctl mount -b /dev/sdb

?
(And if not, what error do you get?)

nb. that you've created a FS on the unpartitioned disk - that's not "wrong" but rather uncommon.

Re: [SOLVED] gnome-disks error mounting filesystem (udisks-error-quark, 4)

https://man.archlinux.org/man/gnome-disks.1 is NOT a tool to mount anything - using udisks isn't another solution, it's the common one.
Multiple GUI filemanagers and little desktop widgets will do pretty much the same.

https://apps.gnome.org/de/DiskUtility/ will most likely require some UID0 leverage like polkit to gain permissions on the device.

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
