Lexar Professional SDXC not opening in sys-usb

Hi, I am trying to open my Lexar Professional SDXC 128GB in sys-usb,
but it returns error, on all USB ports and SD card reader as well.
Other SD cards read nicely. The error I get after trying to open it, is:

Error mounting filesystem
Error mounting /dev/sda1 at /run/media/user/9C33-6BBD: unknown
filesystem type 'exfat' (udisks-error-quark, 0)

On my win7 machine I can open it nicely, but Qubes sys-usb can't open
it. My sys-usb is based on Fedora 30 and is fully updated, like whole
of latest QubesOS.

Any idea how to solve that?

Not really a Qubes problem.
Install exfat-utils and fuse-exfat in to the fedora template.

Thank you, for pointing out the packages. I didn't get fedora-30 to
digest the packages but I found out that debian-10 has it preinstalled
and so I changed the default template to debian-10 and created new
sys-usb through sudo qubesctl state.sls qvm.sys-usb and with the
sys-usb based on debian-10 I am good to go. Thanks again!

If I understand the sec model properly, I should not open the files
directly in the sys-usb but instead channel it to another AppVM and
deal with it there, right?

Correct, and use qvm-block to attach versus the USB device.
