I was developing this game for the GDevelop gamejam #4 and I wanted to export and test on my android device. But some of these PNG images do not visible on the screen. As you can see, the black images (Cave_element_2, 3 & 4) are very similar to the one that appear on the screen (Cave_element_1).
I tweaked the images and exported again to check, but the same issue occurs.
i am testing on Mi 11T with android 13 & Samsung Galaxy Tab S6 Lite with android 13.
If i remember correctly it is due sprite image is too big for android device to handle
Limit was 1000x1000 or 2000x2000x pixels depending on device
But someone confirm this cause i am not 100% sure that was the case
I confirm the limit on recent mobile devices is 2048px.
Without more details on the resources, I cannot comment further.
Is that so? One of the image is about 5000 px 
Sprites that size won’t work reliably (and potentially at all) even on desktop, usually.
It’s been asked about on the forums a few places, but here’s my most recent posts: Large sprite issues - #2 by Silver-Streak
Question about preloading resources - #2 by Silver-Streak
At a high level, just know that sprites generally don’t go above 500x500 in modern games, for memory and rendering purposes. Even Spiritfarer’s sprites stay under that size (and larger screen-sized areas are made up of numerous chunks of sprites so they can load/unload from memory as needed).
