All profiles for one machine disappeared from Cura

[Xeddog 6]

I have been using Cura for many releases now, but upgraded to 4.7 when it came out (2 days), and it was working fine til today.  I have three printers now, and use separate profiles for each although 99% of the settings are common.   The three printers are a Monoprice Mini, A CR-10S, and an Ender 5 Plus.  For a long time I have been launching 3 instances of Cura in my Windows 10 Pro, and when they are finally up and running, I change two of them to other printers so I have one instance running for each printer.   Today, all of the profiles for the CR-0S vanished.  All of them, with one exception and that is the last one I was working with.  I had decided that I would start with a new profile using the default "Standard Quality", but even that one, and all other defaults, are gone.  Now, going back to 4.6, they are gone from there too.    If I select "Manage Profiles, a dialog box is opened, but the list of profiles is completely blank.  

If I change to one of my other printers, everything is normal for it.  All the profiles including the defaults are there, and in the manage profiles dialog everything is there.  Including my CR-10S profiles.   That makes it sound like a pointer for this printer just got buggered up somewhere, but how do I fix it?

You probably created a custom material profile and changed the material type. See https://github.com/Ultimaker/Cura/issues/8229

Yup, It do look like that little beastie.  As soon as I selected a generic PLA instead of my eSun PLA+, they all came back. 

 

Thanks,
