I'm assuming that pathToAttachment resides in either persistentDataPath or temporaryCachePath, as it should. Do you get the same error on other Android 11 devices/emulators? Do other free solutions like this also suffer the same issue?

[dlungor]

On another android 11 devices/emulators the same issue.

Path generated like this:

private static string GenerateNewFilePath(string extension)
    {
        return $"{Application.persistentDataPath}/{GenerateNewFileName(extension)}";
    }

Another solutions doesn't try yet

On android 10 all ok.
