Windows 10: Completed 1909 Security Update-Please Help-Drive Letters R Now Broken

Win version 1909 build 18363.1316

Windows force-installed its 1909 Security Update - When it installed and I opened Windows Explorer I noticed my drive letters are now changed - apparently resulting from Windows somehow mounting something as a CD drive as Drive E (no I don't have PowerISO or anything like that installed).

I did find a category of people, per Google searches, who've had windows add a second CD Drive, but none of the solutions on those results pages have worked (yet).

As it stands, unless I can fix this, it means all the music work I've done is virtually unusable since the projects are pointing at the wrong file locations (meaning that loading requires hunting manually - since my DAW just lists the files, not where they originally were located...) I tried for about 3 hours to Google various queries and followed all the advice (that I understand...) on how to fix this issue but I've yet to sort it.

My DVD Drive is Drive D. C had filled up so the drive on which I have placed a lot of music project data was Drive E. It now shows as Drive F.

Disk Management does not show CD Drive E. (It does show DVD drive D) Or I would simply change its letter and unmount it so I could re-name the original Drive (now F) back to Drive E.

Drive E does not show under diskpart. There may be something there but it isn't clear so even if I tried to remove it in Command Prompt I could do something harmful.

I tried to Eject CD Drive E. (An error occurred while ejecting CD Drive E was the response).

I tried to locate the drive by variously in System/Device Mgr, using view hidden, looking under connections and devices, etc. I tried to uninstall the drives or usb devices that I thought could potentially be this new CD Drive E. And rebooted my computer each time. Did this about 6 times including just now. CD Drive E is still there. In fact, there is a USB Hub that I've uninstalled that keeps popping back up as well. So I have no forensic way - from what I know, to figure out why, all of the sudden, Windows Update decided that I now have

I looked at my list of recently installed programs and nothing seems to potentially be likely to
I installed a demo of a program called WinCatalog2020 a week or so prior, but didn't change anything in it that I think would create a drive image. And the drive doesn't show up in it anyway. The drive (Drive E) doesn't show up in AOMEI Partition manager either.

Any suggestions will be greatly appreciated!

help. USB drive isn't assigned a drive letter.

Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.
