Problem with viewing photos i added to a audio file

Hi Kevin, thanks for your reply, I don't really know how to answer that, I use Rush on my phone Samsung s23 ultra, the photos I use have same specs, I even used some of them several times on the same audio file I am editing, but still have the same problem, I am adding between 20-30 photos in each video I am editing. It's simply an audio file 45 min long , I just add photos of people that are mentioned in the audio file, no motion or effects just putting photos of people when mentioned in the audio file, really simple, again it works fine the first 30 min then it doesn't keep showing the rest of photos I added after the 30th min. If I open the Rush app it's there all the photos as I edited but when exporting then I get this issue on all my 7 projects.  In the app there is not much to do really when exporting. I can chose the quality between (auto, 1080 30 ops, 1080 match framerate, 720 3fps, 720 match framerat) I tried all of them but still have the same problem anyway.
