I have an UMA recipe String basically an XML file and I don't want users to edit the file.

What I have tried:

                characterRecipe = dcAvatar.GetCurrentRecipe();
                FileUtils.WriteAllText(charRecipeFilePath, characterRecipe);

                string recipeFileText = File.ReadAllText(charRecipeFilePath);
                using (Stream recipeFileStream = File.Open(charRecipeFilePath, FileMode.Create))
                {
                    binaryFormatter.Serialize(recipeFileStream, recipeFileText);
                }

I don't get an error, but the file is now empty

Did you check that you actually received some data in recipeFileText? Also, serializing text to a binary file will not change anything; people will still be able to edit it.

I've noticed that. I created a class for some string data and I got an editable text file. I'll try changing the extension to .sav
Thanks

public class UmaInfoData
{
public string UmaInfo_name { get; set; }
public string UmaInfo_class { get; set; }
public string UmaInfo_race { get; set; }
public string UmaInfo_gender { get; set; }
public string UmaInfo_hp { get; set; }
public string UmaInfo_crestName { get; set; }
public string UmaInfo_weapon { get; set; }
public string UmaInfo_shield { get; set; }

public UmaInfoData() { }

public UmaInfoData(string name, string cclass, string race, string gender, string hp, string crestName, string weapon, string shield)
{
UmaInfo_name = name;
UmaInfo_class = cclass;
UmaInfo_race = race;
UmaInfo_gender = gender;
UmaInfo_hp = hp;
UmaInfo_weapon = weapon;
UmaInfo_shield = shield;
}
}

UmaInfoData charInfoData = new UmaInfoData
(
charInfo_Name.text,
classInfo_Text.text,
raceInfo_Text.text,
genderInfo_Text.text,
hpInfo_Text.text, crest.sprite.name,
rHandWeapon.name,
lHandItemName
);

using (FileStream infoFileStream = File.Create(charInfoFilePath))
{
binaryFormatter.Serialize(infoFileStream, charInfoData);
}

You can change the extension to anything you like, it will not change the content of the file. If you make a file available to your users then you cannot easily prevent them from editing or deleting it. What exactly are you trying to achieve here?

Basically, I don't want the player to change the fields in the file directly.
For example the Number of Hit Points: 30

I tried that:
The filepath is: string charRecipeFilePath = Application.persistentDataPath + "/Character Recipe" + "/" + player.name + ".txt";

characterRecipe = dcAvatar.GetCurrentRecipe();
//FileUtils.WriteAllText(charRecipeFilePath, characterRecipe);

using (FileStream recipeFileStream = File.Create(charRecipeFilePath))
{
    binaryFormatter.Serialize(recipeFileStream, characterRecipe);
}

The file Luna(Female)_CIROSTRIX15.txt contains:

   ÿÿÿÿ          Ë{"packedRecipeType":"DynamicCharacterAvatar","name":"Luna(Female)_CIROSTRIX15","race":"G3 Human Female","dna":[{"dnaType":"DynamicUMADna","dnaTypeHash":1673940569,"packedDna":"{\"bDnaAsset\":{\"instanceID\":38920},\"bDnaAssetName\":\"G3HF DynamicUMADnaAsset\",\"bDnaSettings\":[{\"name\":\"BodyDetails\",\"value\":128},{\"name\":\"BodySize\",\"value\":128},{\"name\":\"BodyBulk\",\"value\":128},{\"name\":\"BodyThickness\",\"value\":128},{\"name\":\"BodyHeight\",\"value\":128},{\"name\":\"BodyAnna\",\"value\":128},{\"name\":\"BodyBriley\",\"value\":128},{\"name\":\"BodyCathy\",\"value\":128},{\"name\":\"BodyClarice\",\"value\":128},{\"name\":\"BodyFilia\",\"value\":128},{\"name\":\"BodyGia\",\"value\":128},{\"name\":\"BodyIrelia\",\"value\":128},{\"name\":\"BodyJazmine\",\"value\":128},{\"name\":\"BodyLaura\",\"value\":128},{\"name\":\"BodyLindsey\",\"value\":128},{\"name\":\"BodyMonique\",\"value\":128},{\"name\":\"BodySenna\",\"value\":128},{\"name\":\"BodySunny\",\"value\":128},{\"name\":\"BodyTisha\",\"value\":128},{\"name\":\"BodyUma\",\"value\":128},{\"name\":\"HeadAnna\",\"value\":128},{\"name\":\"HeadBriley\",\"value\":128},{\"name\":\"HeadCathy\",\"value\":128},{\"name\":\"HeadClarice\",\"value\":128},{\"name\":\"HeadFilia\",\"value\":128},{\"name\":\"HeadGia\",\"value\":128},{\"name\":\"HeadIrelia\",\"value\":128},{\"name\":\"HeadJazmine\",\"value\":128},{\"name\":\"HeadLaura\",\"value\":128},{\"name\":\"HeadLindsey\",\"value\":128},{\"name\":\"HeadMonique\",\"value\":128},{\"name\":\"HeadSenna\",\"value\":128},{\"name\":\"HeadSunny\",\"value\":128},{\"name\":\"HeadTisha\",\"value\":128},{\"name\":\"HeadUMA\",\"value\":128},{\"name\":\"BreastSmall\",\"value\":128},{\"name\":\"BreastLarge\",\"value\":128},{\"name\":\"NipplesLength\",\"value\":128},{\"name\":\"NipplesSize\",\"value\":128},{\"name\":\"AreolaSize\",\"value\":128},{\"name\":\"GluteSize\",\"value\":128},{\"name\":\"HipSize\",\"value\":128},{\"name\":\"HeadElfEars\",\"value\":128},{\"name\":\"HeadSize\",\"value\":128}]}"}],"characterColors":[{"name":"Skin","colors":[240,210,159,255,0,0,0,0,255,255,255,255,0,0,0,0,255,255,255,255,0,0,0,0]},{"name":"Hair","colors":[50,30,2,255,0,0,0,0,255,255,255,255,0,0,0,0,255,255,255,255,0,0,0,0]},{"name":"Eyes","colors":[10,11,165,255,0,0,0,0,255,255,255,255,0,0,0,0,255,255,255,255,0,0,0,0]}],"wardrobeSet":[{"slot":"Hair","recipe":"G3F ShortToulouse Hair"},{"slot":"WardrobeCollection","recipe":"G3F JG_FullOutfit"}],"raceAnimatorController":"G3F AnimationCntrlr"}

Most of the file contents can be edited.

Use the debugger to look at exactly what is going on: the most likely reason is that GetCurrentRecipe is returning an empty string, but we can't check that for you - the debugger can show you exactly what it returns, and that's important. It's also possible that your FileUtils class doesn't work properly eiterh, and we have no access to that either.

But ... why are you doing all that?
All you need is this:

C#

characterRecipe = dcAvatar.GetCurrentRecipe();
using (Stream recipeFileStream = File.Open(charRecipeFilePath, FileMode.Create))
{
    binaryFormatter.Serialize(recipeFileStream, characterRecipe);
}
