Unmounting an external drive - error 69888

I am trying to erase and reformat an external SSD drive and I continue to get an error message after trying many trouble shooting ideas from you tube. I think it might have something to do with "removable volume"

Has anyone else has this problem. If so, were you able to solve it?
