Plasma activity lost after recent upgrade

Hello,

it’s probably a noob question and I’m sure the wording will be lacking, but please bear with me.

I had up until yesterday I think (unfortunately I don’t look at the desktop too much, just when I actually need it) an activity configured with some widgets instead of seeing the desktop icons.
Today I turn up my system and I caught a glimpse of the desktop and noticed that the activity with the widgets is gone. In its stead there is the icons of the desktop directory all over the default wallpaper (I had a set of random pictures).

Is there any possibility to recover the configuration of my activity or is gone for good?
Is this an expected behaviour of some recent update (I have a VERSION_ID=“20200413”) or a bug of sort?
