After attempting to add Raspberry Pi OS to my SD card using Raspberry Pi Imager v1.5 on Windows 10, the install abruptly threw an error about a third of the way through writing. Now the SD card cannot be found on either Windows 10 or OSX disk utilities. Has anyone come across this error before and found a remedy?

I purchased this kit and am using the 32 GB SD card provided with the USB adapter.

(Note: I'm not asking how to remedy a 'lost' SD card -- I know that's outside of this forum. That said, off-hand suggestions on the subject are welcome :-) )

I'm not quite sure I understand all of your question - e.g. when you say "attempting to add RPi OS to [your] SD card". I think you should have only one image installed on an SD card.

Next - SD cards are not the sturdiest things, so it's always a possibility that it has simply failed. If it were me, I would try again:

  1. You might try rufus instead of RPi Imager. I've not tried RPi Imager, but rufus has been around a while longer & has a good reputation.

  2. Download a fresh image from the RPi download page

  3. Use rufus to write the image file you've downloaded to your SD card.

After you've successfully written the image to your SD card, the only thing you will "see" in Windows or macOS will be the boot partition (boot is formatted w/ FAT32, whereas / is ext4). Follow the steps you took before (creating a blank file named ssh in boot, etc.). Plug it in, and try to boot again.

I was able to solve this issue by rerunning the Pi Imager (v1.7.3) as Admin on Windows 10. When I ran the Pi Imager with standard permissions I also received the write error which made the SD card unrecognizable by Windows. Rerunning the Pi Imager with Admin allows the process to complete successfully.
