So I have accidentally corrupted a sandisk usb drive. When I go to Disks & Devices, the usb is not detected there. I can access it only through kde partition manager or the terminal but I am unable to read any data in it. It is supposed to be 64GB but in kde partition manager, the capacity is shown as 64MB. I tried creating a new partition table, it shows success but the partition table doesn't get created. It still prompts me to create a new partition table. How do I make the usb drive usable? I don't care if the data is lost.
I tried the previous answer to a similar question How to format a USB drive?
It didn't work for me. Here is the output when executing those commands.

Even though fdisk says a new partition was created, when rechecking afterwards with lsblk it doesn't show any new partition.
