Hi Nikki. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.
Have you tried all of Seagate's published troubleshooting steps here:

It's not on the list as supported for Windows 11:

Recovering data:

You can always crack open the case and remove the drive to plug it into SATA internally. But I'd get the data off first from a Windows 10 PC.
Feel free to ask back any questions. If you'll report back results for each step it can help determine what else needs to be tried. I will stick with you until it is fixed.
