"Please Insert Disk into USB Drive" Error message

Question

I have been using a free 3rd-party program called IMGBurn for copying the contents of old CDs and DVDs onto. The program is old, but is still recommended by every website I can find and by many people on the internet (I once saw a MichealMJD video in which he mentioned that he had been using the program for 8 years). I had already copied a lot of CDs and DVDs onto the drive, and was copying another. While I was copying this one, I had actually copied its contents to a folder on USB flash drive before and then was copying the contents of that folder to an ISO image, as the program had issues creating it from the drive directly. While using the program, it gave me an error message saying that it could not write to the image file as the drive did not exist. Opening up file explorer showed that the flash drive/pendrive wasn't there. I had figured that it had came out of the USB port, as it had been in there for a couple hours. Plugging it back in and opening up the pen-drive displays an error message "Please insert disk into USB drive E:." This confused me, but I had figured that the drive had been placed in drive E:. Forcing it to use drive E: does nothing. I am running Windows 11 22H2 and I had used the drive before with no problems. Please help, I have 40gb+ of data on the drive. The drives total capacity read (before this happened) to be at ~59 GB, which means more like ~59 GiB.

Answer 1

Disk manager tells me that there is no media in the drive. This makes no sense, as it is a USB flash drive.

Answer 2

Is that drive visible in Disk Management, and shown as healthy?

Or has it failed?
