My Save Gone

[hrzxleonard]

My original save file is still in the old folder, I renamed the old folder to reinstall my Stardew Valley, after I reinstalled the application I tried to rename the old Stardew folder, but it didn't work, the application would crash if I clicked the load button on the start menu, and the application also crashed when creating a new character, then I tried to rename the old folder and made the Stardew folder empty, after that I moved my old save into the empty folder, Stardew Valley doesn't crash when I press the load button or create a new character, but the old folder that I moved is not detected or disappears, even though the folder is there :(

please provide a solution to this problem, I'm using android
