I can't eject CD from my Mac Pro M1 neither see the disc
I was testing my new camera, importing images through a memory card reader. After that, I forgot to eject the disc from iCloud in Finder (or the file I don't know how to call it). Then my Mac notified me about ejecting the disc but when I plugged the reader in I could not see the disc. I tried restarting and shutting down but none could make it appear again. Please help.
MacBook Pro 13″, macOS 14.5
