Can not format USB sticks

It seems it is related to the latest kernel update:

Gparted - Libparted error

I reinstalled EOS XFce on a computer with SSD, mounted the partitions in the etc/fstab, rebooted the computer. To see if everything fits, I started Gparted and got the following message window: [Bildschirmfoto_2020-09-11_00-42-23] I have 3 partitions on sda: EFI Boot, root and swap What is broken here?

Partitions ... have been written, but we have been unable to inform the kernel of the change

Partitions … have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should probably reboot now before making further changes. This is happening in both gparted & gnome-disk-utility on all of my disks (OS, data1, data2, etc…). Rebooting and then using either program results in the same error. I’ve never had this error before, and I don’t want all of my harddrives ruined. What…

Seemingly it will be fixed with the next one.
