### Steps to reproduce

1. Add AudioStreamPlayer to the scene.
2. Create script my_interact.gd:

extends AudioStreamInteractive
class_name MyInteract

3. In the AudioStreamPlayer create new MyInteract resource → add any .ogg\.wav\.mp3 to attached resource
4. Autoplay = true.

Variant 1 : crash project :
5. Run scene (F6), close window while sound is still playing.
6. Repeat item 5 3-5 times and get CrashHandlerException in console

i test it on my second pc with win 10 and editor crashes too (win 11 only project) and on win 10 i got popup window:


original text:
Инструкция по адресу "adress" обратилась к памяти по адресу "adress" память не может быть written.
english:
The instruction at "adress" referenced memory at "adress". The memory could not be written.

Variant 2 : crash editor :

5. Playing = true.
6. Ctrl+Shift+Q (Quit to Project List)
7. Repeat 3-5 times and get editor crash with same as variant 1 CrashHandlerException

### Minimal reproduction project (MRP)

[112480.zip](https://github.com/user-attachments/files/23415567/112480.zip)

Start by running the attached 112480.zip reproduction and inspect the shutdown backtrace through modules/gdscript/gdscript.cpp, core/object/object.cpp, servers/audio_server.cpp, and core/templates/safe_list.h. Reproduce both project and editor shutdown variants repeatedly; done means closing while the AudioStreamInteractive stream plays no longer crashes.
