issue with .source() at 0.12.0

Trying to read from that source causes OperationNotPermitted error

Hi @T8RIN! Can you share a sample project that reproduces the problem? Thanks a lot for your help!

@Composable
fun rememberDocumentPicker(
    maxItems: Int? = null,
    extensions: Set<String>? = null,
    onSuccess: (List<String>) -> Unit
): ResultLauncher {
    val picker = rememberFilePickerLauncher(
        type = FileKitType.File(extensions),
        mode = FileKitMode.Multiple(maxItems),
        onResult = { files ->
            if (!files.isNullOrEmpty()) {
                onSuccess(files.map { it.path })
            }
        }
    )

    return remember(picker) { ResultLauncher(picker::launch) }
}

after calling PlatformFile(path).source().buffered() and attempting to read i get the issue

suspend inline fun String.chunkedFileRead(
    chunkSize: Int = CHUNK_SIZE,
    onChunk: suspend (ByteArray) -> Unit
): Boolean {
    val openedSource = PlatformFile(this).source().buffered()

    openedSource.use { source ->
        var endReached = false
        while (currentCoroutineContext().isActive && !endReached) {
            val chunk = try {
                source.readByteArray(chunkSize)
            } catch (_: EOFException) {
                endReached = true
                source.readByteArray().also {
                    if (it.isEmpty()) break
                }
            }

            println("chunk size = ${chunk.size}")
            onChunk(chunk)
        }
    }

    return true
}

Weird thing that this only happens when PlatformFile is recreated like

val file: PlatformFile = .. //from documentPicker

file.source() // ok
PlatformFile(file.path).source() // not ok
