Error : USB could not be created at this time

Hello,

I have a problem for the creation of a bootable USB.

After 20 secondes, an error message appear on the first task : "USB could not be created at this time" (Impossible de créer de lecteur USB pour le moment).

The version of DIA is 11.1.2.4

The error appear for Dell Image Static or Dynamic with both the option to "Create a dynamic Image" or "Create a USB Key".

After this error, i can see that a partition has been created ont the USB Key .

I have tried on several USB key/PC.

I have tried to modify the config file as show in this post : https://www.dell.com/community/en/conversations/image-assist/not-posible-to-create-bootable-usb-to-deploytest-the-image/647fa318f4ccf8a8de8d78a6
