Unable to save / unable to load files

Hello! So I have some problems today with my project.

First, I noticed I couldn’t save my project anymore

(in english : unable to save project / there was an error during the saving of the project, please try later)

Then, when I launched preview of my game as usual,all my sprites/background/elements of my game were gone and there was a blank background with weird color blocks instead (my characted was replaced by a color block).

Then, I launched débogeur (french version to the thing who detects errors/bugs) and there was lots of errors saying exactly the same thing for different sprites :

So I asked myself : is this error the reason I couldn’t save my project or launch a preview ?

My hypotheses on the origin of the problem is :

  1. I did the error (newbie error) to move some sprites files in my computer (I wanted to arrange them differently) while they were already load in G Develop.
  2. I sorted the exprimental/useless sprites that I had created and deleted from my object’s list (so they weren’t on my game) but were still present in my ressource library

But if everything is 1° explanation, G Develop don’t let me fix that : I can’t load any new files in my sprites properties and this message appears :


(in english : there was a mistake during the sending of some ressources / verify your internet connexion or try later )

Anyone has an idea of what can i do ?

PS : my project is stored in G Develop Cloud, some of my sprites are too (created with Piskel on G Develop) so even the sprites stored on GCloud seems unable to be loaded even though they exist in my ressources library.

Edit : It works again ??? I closed G Develop Editor website to re open it & re open my project, G Develop proposed me to open : either my manual saving, or G Develop automatic saving.
I chose to open my manual saving from yesterday, and everything seems back to normal ?
