Timelapse footage missing after recording on iPhone

On Monday, June 23, 2025 i have recorded a time-lapse which i was making for about 30 minutes. Once i stopped shooting and went to the library to check the results i saw that there are no time-lapse footage at all. I restarted my phone but nothing appeared. I have definitely made it, because my screen was always on, the circle was spinning and time was going. This is really unfortunate as I have no clue how it could have happened. Also, phone has plenty space and trash dosnt have it either. So I checked everything on my side. Any ideas?
