You might have used incorrect filename for your downloads with illegal characters:
try this kotlin code to replace your download file name :

fun sanitizeFileName(fileName: String): String {
            // Define a regex pattern for characters not allowed in Android file names
            val regex = "[/\\\\?%*:|\"<>]".toRegex()

            // Replace all occurrences of the disallowed characters with "_"
            return fileName.replace(regex, "_")
        }
