What is the expected behavior?

Files in the directory in developer mode should not be lost

What is the actual behavior?

I started nvs encryption in developer mode. This is my file system. The files in the directory existed after the first encryption, but when I used idf.py encrypted-flash monitor again, the files in the directory were lost.

Below is my specific file code information

// 初始化 LittleFS 文件系统

    // 列出文件
    list_littlefs_files("/littlefs");

// 检查加密后的文件系统是否正常工作
FILE* file = fopen("/littlefs/index.html", "rb");
if (file == NULL) {
            printf("Failed to open index.html for reading\n");

} else {
    fclose(file);
    printf("Successfully opened index.html\n");
}

}

When I decrypt the firmware, the code exists without modifying the files in the directory.
Below is my encrypted partition.This problem will not occur if you use spiffs

Name, Type, SubType, Offset, Size, Flags

nvs, data, nvs, , 0x8000,
fctry1, data, nvs_keys,, 0x1000, encrypted
otadata, data, ota, , 0x2000,
phy_init, data, phy, , 0x2000,
ota_0, app, ota_0, , 0x1B2000,
ota_1, app, ota_1, , 0x1B2000,
storage, data, littlefs,, 0x68000,
fctry, data, nvs, , 0x6000,

meuconfig setup

Steps to reproduce.

1.Initialize the esp_littlefs file system
2.Encryption developer mode
