No Locales were available

same issue continue.

 

any of them worked, i tried all of them

I resolved it by unchecking split by application binary inside player settings

 

I think I found the reason of the bug.
After enabling full exception support with stack tracing, I found out that inside the file

com.unity.addressables\Runtime\ResourceManager\ResourceProviders\TextDataProvider.cs

,
line 165 (may be different depending on the version, I'm using the latest version currently, 1.4.3 Localization, 1.21.9 Addressables), where it says:

UnityWebRequest request = new UnityWebRequest(path, UnityWebRequest.kHttpVerbGET, new DownloadHandlerBuffer(), null);

, up to this point the variable

path

holds the wanted URL, but inside UnityWebRequest it ends up with the Exception

System.UriFormatException: Invalid URI: The URI is empty.

There must be a bug when using a string path. If instead we pass an URI, like this, it works:

UnityWebRequest request = new UnityWebRequest(new Uri(path), UnityWebRequest.kHttpVerbGET, new DownloadHandlerBuffer(), null);

I replaced

path

with

new Uri(path)

This may be the reason why it seems to work with different Unity versions, but I have no idea.

I'm sorry, I don't have time to make a bug report right now. I fixed it on my end though, by modifying that line in the addressables package.
