I was making a few updates to some surveys this morning, and suddenly Survey123 Connect was not finding my survey designs. As in, I cannot open the surveys at all. I checked, and everything is there in C:\Users\lberni\ArcGIS\My Survey Designs.
Here's the warning when I try to open a survey:

Also, any new surveys that I just created are not showing in Connect at all. They are, however, being saved in the My SurveyDesigns folder.
I'm using Connect v 3.0.142, which I updated to several weeks ago.
This is very disconcerting.
Please advise asap.
Thanks,
Lynn
