I had the same problem. I re-installed Windows 10 on an SSD and the hard drive didn't show up in Windows after re-connecting it. I installed EaseUS data recovery software and it saw the hard drive. I didn't try to recover anything. I rebooted the PC and then Windows saw the hard drive. I'm not sure what fixed it but it appears to be a common problem. My PC is 6 years old.
I just installed EaseUS, and it sees the hard drive as "Lost Partition1"

I was never a fan of EASE US, I always preferred Partition wizard, but can you format it somehow?
Try running windows installation boot and format it from there, if it doesn't recognize it there or says some kind of error, unplug your other hard drives/ssds and try it again, if that doesn't work then I don't know.
