That Cryptex is part of macOS. It isn’t normally visible, but it’s also not a problem.
Based solely on the filename name and the timing — and without digging further — I suspect that’s a background security improvement containing the eMudhra certificate revocations.
Irrespective of this cryptex, do update macOS.
Cryptexes are basically digitally-signed disk images containing trusted code and data for macOS or for Apple apps such as Safari, and the design is intended to isolate the code and data from causing or incurring issues.
What Apple calls background security improvements are just what it says on the tin.

The volume "Creedence" is a valid OS volume that is typically hidden from view.
For some reason and under some circumstances it does become visible. You can safely eject (unmount) it from the Desktop by selecting it and then pressing Command-E (⌘E).
A simple restart of your computer may resolve the problem.
You might also update your 10.15.7 Catalina OS installation to the latest and current 10.15.8 that was released back in February.

Post a screenshot of Disk Utility (with "Show All Devices" selected in the View menu), including the sidebar of the app, with the Credence volume selected.
Have you looked to see what's in the volume/drive?

I had to force the ejection to have it out of my desktop, yesterday. Today, restarted the IMac, it is here again. In the meanwhile, between my first message and this one, it duplicated (two icons!)
