GUI editor breaking whole app (maybe the new sprite feature)

Hi,

I tried the new GUI sprite feature and since I couldn't find any documentation, I tested it by uploading a random picture and putting in random numbers.
The testing client works and launchs normaly. The app works properly until I open the GUI with the sprite (and two slots and text field).

After restarting the app works fine (until I open that one specific GUI)

Thanks you for any response!

PS: I'm using version 2024.4.52410
