Hmm. Not sure wha that means. Was there anothed disk in the VG ?

The sizes don't match. The size of /dev/sda5 is 476 GiB but the PV
within claims its size is only 55 GiB and is almost full. Did you reduce
the PV size in /dev/sda5 with pvresize ?
Now you need to explain what you want to do exactly, because you have
been unclear so far.
Do you want to reduce the partition /dev/sda5 and create a new plain
partition for whatever use (filesystem, new PV for existing or new VG) ?
Then you must reduce /dev/sda5 with whatever partitioning tool, to a
size of at least the PV size, 55 GiB (*not* 55 GB which is only 51.2
GiB, beware if using parted). In the free space on the disk you can
create a new partition.
Or do you want to create a new LV in the existing VG ?
Then, if the new LV size is less than the remaining free space in the VG
(about 6.5 GiB), just use lvcreate to create the LV. If its size must be
bigger than the available free space, then you need to resize the PV
first, up to the size of /dev/sda5.
