MacOS Ejects All DVDs, CDs

Two months ago, my mid-2014 15" MacBook Pro Retina running Catalina stopped reading all discs inserted into my Superdrive. I bought a new one, thinking was a hardware problem. The issue remained. I have since upgraded to a 16" M1Pro MacBook Pro running Monterey and still the problem persists. When the Superdrive is plugged in, I can see it in System Information // Hardware // Disc Burning. When I insert disks -- no matter what disk or type of disk, purchased CDs, purchased DVDs, blank CD-Rs... -- the drive whirrs for a bit, then spits the disk out. Strikes me, thus, as some sort of software conflict? Any ideas or suggestions welcome.

Boot to Safe Mode. That boot up takes minutes and clears caches and other things like many things do not load and thus will help determine if software conflict and may resolve your problem.

Can you test the drive on another computer?

Are you connecting it directly to the Mac?

I had tested the drive on other Macs and was/am connecting directly to the computer (rather than a hub). I also had booted my old computer, the Intel MBP, where the problem began, in Safe Mode and the problem persisted. But I've just done it again on the current M1Pro MBP and it worked! The computer recognized, rather than spit out, discs in Safe Mode. And continues to so after rebooting normally. Thank you!

This fix didn't last long. MacOS stopped reading discs again. I booted in Safe Mode again, resolved problem again. Occurred yet again, though, and now not resolving by booting in Safe Mode -- that is, even in Safe Mode, MacOS is ejecting disks before mounting them. Other suggestions?

I have a Pioneer BDR drive which is recognized and reads BDRs with Monterey 12.1. I haven't tried burning discs as yet.
