Most of my photos disappeared!! Help

Hello all, Please help me, Ive lost most of my photos (I didnt delete). Most of my photos especially past 3 months are gone, cant find them in gallery, in file manager, or any place else!!!! What is weird is that my cover and home screen photos are 2 of them, and they are still there, but the source file is gone. I use Xiaomi Mi 10.

Please help I lost photos of my last vacation with mt lil kid ;(

Thanks in advance
