I've seen no evidence of an intentional fix. For me, it was fixed on the second version update after it happened. It looks like it's related to updates in some way, as that's when it started for me and others. I'd still REALLY like to know what the cause and resolution is as I'm confident it will happen again.

For me the problem occurred on Win10 after an update from MS which added Ransomware Protection. To make the optical drive's visible again I could either disable the Ransomware Protection completely or just add the Makemkv exe files as an exception. I chose the later option and now Makemkv works again.

You'll find it in Windows Defender Security Centre under Virus & Threat Protection.

It's my 1st post, and I'd just like to say Thanks! I've been fighting the same problem and it was the ransomware protection. I followed your advise, added an exception, and it fixed the problem. It also worked for PowerDVD18 not working also. Thanks again. :)

Yes. Windows Defender was the offender. Specifically Makemkvcon64.exe was getting blocked. I had a feeling it was local to my machine and some change that took place without my knowing. Thanks for your help. I'm back up and ripping. YAY!!!
