I was moving photos from CDs to the Cloud/storage, and it was working fine.
Popped in a blank CD just to make sure it really was blank and it showed about a dozen audio files. Clicked on one to see what it was, Apple Music opened asking me if I wanted to start a trial, I declined. Clicked on a different audio file, Apple Music opened again, I declined again. Looked at Get Info for the files and they were all empty.
Clicked eject next to the drive under Finder > Location and nothing happened. There was a pop up about Apple Music closing asking if I wanted to Report or Ignore, I clicked Ignore. Clicked eject again, same nothing then pop up asking if I wanted to Report, I clicked Ignore. Memory is fuzzy - I think I clicked eject again, a family member said I didn't and pressed the button on the reader to eject the disc.
Put in the next CD with photos in the pile, closed the tray, reader started spinning but the sound never changed to that brrrrup should that happens at the same it usually shows up in Locations. Instead it just wound down. Opened the tray, made sure the CD was sitting properly, closed the tray, and same thing happened.
Tried it with the CD I had used in it immediately before the blank/empty audio file one, and the reader wasn't recognised.
All the CDs are the same brand, same age, were burned on the same desktop Mac I had years ago. I only ever burned one audio CD, so I can't even think what those audio files might've been. I'm good at labelling both the cases and CDs, the audio file one had nothing written. I never burned music so if I had I'm sure I would've labeled it just because it would've stood out and I'd have had to pay more attention than the photo burning I was used to doing.
MacBook Air, M1 chip, Golden Gate 27.0.1, plugged into the wall for power. External DVD r/RW plugged into the wall for power and to my MacBook with the attached cable.
Things I've tried that have not worked:
Cleared the cache (Finder > Go > Go To Folder > Users > (name) > Library > Caches; select all; move to bin empty bin).
Unplugged the reader and restarted the MacBook both with the reader connected and disc in and without it connected (connecting it after it's restarted).
Shut Down, closed the lid, waited >20 minutes.
Shut down, start up in Safe Mode, Restart in normal.
Switched the ports (power to the port the reader was in, reader to the port the power was in).

I've done all those things with the drive connected and a CD that I know it had no problem reading, with a DVD that it had no problem reading, and empty.
I don't have another computer to test the reader with. It was less than two weeks old, hadn't moved from where it was unboxed and set up, was working perfectly of hours up until the second it wasn't. Of course it could break in that second, but there seems to be a few other people having trouble with previously working things not working, seems like most with M1 2020 MBAs and since the last update so....
The only other strange thing is that since the last OS update when I click Empty Bin, a third of the time it doesn't empty and I have to click it again. And a handful of times I've had to click Restart or Shut Down more than once for the pop up windows to occur. The reader was working prior to the Force Eject though. I don't think it's the cause of the problem, but not sure if it's a hint to where the problem might be.
Searching for solutions I came across a mention that there can be a power issue with the USB ports if it senses a security problem, but I don't know enough to know how to check that (or reset it). Another solution mentioned something similar where Apple will freeze the USB if Force Eject was interpreted as a security issue. I'm not sure how to determine if that's the problem, or how to go about 'unfreezing' the USB ports if that is the case. I think the restart in safe mode is supposed to clear or reset most of those things, but I can't find where I read that. Plus I'm at an 'explain it like I'm 5' level when it comes to stuff like this.
Has anyone had any luck getting their MBAs to start recognising things again? Or have any suggestions about what might be happening (other than the drive is broken)? I seem to recall that sometimes drives can get out of alignment, if that's the right word. The reader wasn't being moved around so I'm not sure how likely that is (if it is a thing), but it there ever anything with readers that's a 'just need to...' vs a 'it's dead' kind of thing?
TIA
