Qubes 4.3 - usb GUI shows attached - usb is not attached in dom0

Hello,

Situation:

I have a nvme connected via thunderbolt to Qubes 4.3

it is listed on USB GUI

this is used for backups
thus, i tried to attach it on dom0:

sudo qvm-usb attach dom0 sys-usb:3-1-1

but, it does not show-up on dom0 - lsblk does not show this new disk

.
I check via command-line, and it is not attached:

sudo qvm-usb

However, on the GUI for USB devices
this USB nvme disk is shown as attached to dom0

How can I troubleshoot this error?
i rebooted
i tried using this USB disk through another AppVM but it fails midway while writing the backups.

Fixing this is really important - to resume backing-up my system.

Please let me know if further info is required.

Many thanks,
