Problem with android studio pictures?

Question

Mobile development

Hello, I hope only for you. The problem is that in the project that I am doing, supernatural things have begun to be noticed right away (I can’t call them otherwise). I insert a picture in the project, which has been in the drawable folder for a long time - everything is fine. I insert the new one that I put a few minutes ago in the same folder - the application gives an error from the phone when I test it. With old pictures everything is fine, with new ones - such a disaster. All downloaded from the same resource, with the same resolution and almost the same weight.
Now I even tried to just copy the old picture that worked, rename it and paste it back - it also stopped working, for one thing its old version stopped fussing.
I have a lot of pictures (30+) in drawable, maybe this is related to this folder itself or the program as a whole. Or maybe I'm stupid and don't see something.
I repeat, the old pictures, already used - everything works without problems, with the new ones - it just gives me an error when I go to the application page where this picture is.
Perhaps someone came across such supernatural activity, rummaged through everything, found nothing.
Thanks for the help.

In general, the problem was in the RAM of the device itself. I changed the pictures in size 2 times smaller and it helped.
