Steps to reproduce

App launched with --verbose option and quitted

tryed to add queue_free() in

func _exit_tree() -> void:
    thread.wait_to_finish()

heres what th ready function looks like as i first incriminated the thread:

func _ready():
    thread = Thread.new()
    thread.start(self._on_message.bind(null))

    get_viewport().files_dropped.connect(Callable(self, "_on_files_dropped"))
    _relay_client = $WebsocketClient
    _relay_client.connect("on_message", Callable(self, "_on_message"))
    _relay_client.connect("on_players_ready", Callable(self, "_on_players_ready"))

    $StartScreen/StartGameButton.connect("pressed", Callable(self, "_on_start_game"))

    $StartScreen.show()
    $Lobby.hide()

and here's the _on_message one

func _on_message(message : Message):
    if (!message) : return
    if (message and message.disconnected_closed): return
    if (message and message.disconnected_disconnected): return
    if (message and message.server_login): return
    if (message and message.match_start): return
    else:
        if (message.content.has("seed")):
            process_message(message)

        if (message.content.has("whoiam")):
            process_whoiam_message(message)

this is fixed on 4.2

[akien-mga]

I confirm that @superherointj's MRP reproduces the bug in 4.1.2, but it's fixed in 4.2-beta5.

akien-mga, thanks for testing.

Just tried Godot 4.2-beta5, commit: 4c96e9676, but error persist. Logs: https://termbin.com/fh59 I have updated repository to version v4.2.rc2 (error persists).

Have you tested on Linux? [I'm trying to understand why it works for you but not for me.]

[joined72]

I confirm the bug on 4.2 stable too! :( Please fix it asap.

We are doing the best we can, but we have little details on what is causing this, please provide more details on what platform you are on

It's also not a serious bug, so less likely to get any major focus, no pressing need to "fix it asap", it'd be nice to fix it but without someone identifying what's causing it it's not as easy

Download the following asset demo project, run it, eat an apple in the game and close it, you will see the error. asset demo project

Yes I understand, excuse me please.

Good choice if I may (except I'd have gone straight for debian 😀)
