Deleted and reinstalled app to fix issues—now photos from last 3 months are gone

I’ve been having issues with the OneDrive app for iPhone (I have a 16 pro and I’m on the latest iOS and onedrive software update). Last night, I tried deleting and reinstalling the app to see if it would help resolve the issues. Instead, all of my photos from January 25 until now were gone! I haven’t checked my laptop to see if I can see them from a desktop, but I’m freaking out. You can even see that my folders show a much larger number of files based on the size, but I can’t see the photos that should be in the folder. How can I fix this??
