minecraft world wont open, no matter what i try

although i have no resource packs active in this world, when i click on it it just says loading resource packs for about 20 seconds, never starts building the world and then crashes the game. i have spent many months working on this world and its really upsetting to see something im so proud of just disappear, i have plenty of storage on my phone and a good sized ram amd have even tried clearing more storage both on my phone and from minecraft itself to see if this would fix the issue but it just hasn't, i just want my world back
