Something very weird and dangerous happened today on my Ubuntu 24.04 laptop.
First I used normally all my USB drives, including creating startup disks on one USB stick.
Then I inserted an almost new Kingston Data Traveller 32GB. Format it with ext4 + LUKS using:
gnome-disk-utility 46.0
UDisks 2.10.1 (built against 2.10.1)
It got stuck during the formatting, and the the Drive just disappeared from everywhere. It's not there even using fdisk or gparted. Nothing.
What is worst is that now the system can't read any USB drive at all. It's like the formatting operation messed up deeply with the ability to even read - not mount - USB storage.
I am confident that all would be fixed with a reboot, but I would really like to understand what happened as it's the worst thing I've seen on happening on Ubuntu/Linux since a very very long time.
--- Update
Collecting more data. I've reboot, now it all works.
I'm following dmesg and here is when I connect the drive
[ 231.076775] usb 4-2: new SuperSpeed USB device number 6 using xhci_hcd

And then I open file manager, select drive, get prompted for the password, insert password and BOOM:

From now on, USB is no more :( If I insert another - fully working - drive, it says this:

So I try to format it again with Ext4/LUKS, and again it gets stuck and breaks USB until next reboot. Now I have the actual dmesg log of when it happened:
