const createOfflineResponseDataFile = async () => {
  try {
    // Check for write permission
    const permissionStatus = await Filesystem.checkPermissions();
    alert("Permission status:" + JSON.stringify(permissionStatus));
    if (permissionStatus.publicStorage !== "granted") {
      const requestStatus = await Filesystem.requestPermissions();
      if (requestStatus.publicStorage !== "granted") {
        throw new Error("Write permission not granted");
      }
    }

    const result = await Filesystem.writeFile({
      path: OFFLINE_RESPONSE_DATA_FILE,
      data: JSON.stringify({}), // Initial empty data
      directory: Directory.Documents,
      encoding: Encoding.UTF8,
    });

    if (result) {
      return {
        status: true,
        message: "File created successfully",
        result,
      };
    }
  } catch (e) {
    alert("Unable to create file" + (e as any).message);
    return {
      status: false,
      message: "Failed to create file",
      error: e,
    };
  }
};

Filesystem.checkPermissions() method returning publicStorage: “granted” but unable to write file. Testing on android 13. Device samsung.

First off, you need to fix your mismatch versions of Capacitor. You’ve got @capacitor/android and @capacitor/core v7 but @capacitor/filesystem and others v6.
