Cannot rename camera profiles any more

Apologies for not being more specific.

• I created a custom camera profile using ColorChecker Passport, using the LrC plugin.  It created the profile as "Untitled Profile.dcp" in the `%APPDATA%\Roaming\Adobe\CameraRaw\CameraProfiles`
• There is no option to rename or remove a camera profile. In LrC right click does not bring up a context menu at all, for ANY profile.  In the CameraRaw dialog in Photoshop right-click displays a context menu but there's no option to rename a profile.
• I tried renaming the .dcp file, but LrC did not pick up the name.  In the profile browser it is still "Untitled Profile".
• I quit LrC, made a copy of the .dcp file and renamed the copy to the desired name. Upon relaunching LrC, the additional profile does not appear, only the original "Untitled Profile"
• I then moved the copy to my Desktop and tried importing the profile into LrC.  It complained that the profile already exists.
• Looking at the "Untitled Profile.dcp" file in a hex editor (it's binary) I note that there's a profile name at the end, null-delimited (i.e. no string length field), so I updated the string to the desired name and also changed the file name to match.
• That profile disappeared from LrC's camera profile menu

I gave up and created a standalone profile using the ColorChecker desktop app from the same image (i.e. not using the ColorChecker plugin).  The app prompted for a profile name (which the plugin didn't), and it created the profile, with the correct file name and embedded name, in the %APPDATA% CameraProfiles folder.  Upon relaunching LrC, the new profile appeared in the menu as expected.

I've resolved my particular issue, but the fact that there's no option to rename a camera profile needs to be resolved.

None of the information in https://www.lightroomqueen.com/community/threads/how-do-i-rename-a-customised-created-colour-profile.38001/ from 2019 seems to work any more.

In CameraRaw (accessed from Photoshop when opening a .CR2 file) there's still no "Rename" option (and no "Delete" either).  I presume just delete the .dcp file for that. 

Also, the links say "... in Camera Raw..." but I can't find a way to launch Camera Raw on its own, the only option I've found is to try opening a raw file in Photoshop.  Is there another way to launch Camera Raw?
