OBS Studio crashing when switched to scene (Python Script)

[Nocticae]

Hi,

I have a problem with my python script...
I've got 4 scenes : 'Scene_0' à 'Scene_3'

Situation 1 :
I'm in scene 'Scene_0' when I switch to scene 'Scene_1'
The script returns me to the 'Scene_2' scene.

In this situation, the program works perfectly.

Situation 2 :
I'm in scene 'Scene_0' when I switch to scene 'Scene_3'
After 10 seconds, the script normally returns me to the 'Scene_2' scene.

But in this case, the application no longer responds, I don't know why there's
no error message, no crash log, nothing.

Here's the code :

import obspython as obs

### Variables ###
countdown_time = 0
################

###### OBS ######
def script_description():
    return "Un script de compte à rebours pour OBS Studio."

def on_event(event):
    if event == obs.OBS_FRONTEND_EVENT_SCENE_CHANGED:
        assigning_functions_to_scenes()

def script_load(settings):
    obs.obs_frontend_add_event_callback(on_event)
#################

##### Scipts #####

def get_currentscene() -> str:
    """Gets the current scene and returns its name"""
    current_scene_as_source = obs.obs_frontend_get_current_scene()
    current_scene_name = obs.obs_source_get_name(current_scene_as_source)
    obs.obs_source_release(current_scene_as_source)

    return current_scene_name

def set_scene(scene_name: str):
    """Gets scene name and set new current scene"""
    source = obs.obs_get_source_by_name(scene_name)
    if source is not None:
        obs.obs_frontend_set_current_scene(source)
        obs.obs_source_release(source)


def assigning_functions_to_scenes():
    """Calls a function according to the current scene"""
    Current_Scene = get_currentscene()

    if Current_Scene == "Scene_1":
        set_scene("Scene_2")

    elif Current_Scene == "Scene_3":
        global countdown_time
        countdown_time = 10
        obs.timer_add(Countdown_to_scene_change, 1000)

def Countdown_to_scene_change():
    """Countdown which at the end will call the set_scene function"""
    global countdown_time

    if countdown_time > 0:
        countdown_time -= 1

    else:
        obs.timer_remove(Countdown_to_scene_change)
        set_scene("Scene_2")

The Advanced Scene Switcher plugin can probably do all that for you, and it's pretty well tested already.

Advanced Scene Switcher

This plugin will allow you to automate various tasks using "Macros". Macros consist of a list of conditions under which a list of actions will be performed. Examples and guides can be found in the wiki. Feel free to contribute! If you run...

obsproject.com

• Macro 1
  • Conditions
    • Current scene = Scene 1
  • Actions
    • Switch to Scene 2
• Macro 2
  • Conditions
    • Current scene = Scene 3 for 10 seconds
  • Actions
    • Switch to Scene 2

It seems odd to switch immediately away from a scene every time you enter it. Is there a reason for that? Why not switch directly to Scene 2, and not even have Scene 1?
