If this happens often, you can disable write caching for that drive. It’ll feel slightly slower (since it’s actually operating at the speed of the hardware instead of caching operations in RAM and gradually writing them to disk in the background), but you’ll be able to remove the drive almost instantly.
I used to find it had something to do with the explorer thumbnailer finishing up but sort of not letting go. It would happen if I had pictures or videos on the USB drive, and if I got the error I could go to another folder like my documents, drag a picture into another folder, go look at the pretty new thumbnail, then I could remove the USB drive because the thumbnailer was ‘parked’ back on the C drive. Sounds like I’m making it up but I swear it worked.
