Can't load a level using scene changer, but it works if I just preview the individual level

I’m making a 3d game full of .glb models, and when I try to exit a level to another certain level using the scene change, it just hands on the loading bar. But if I go to that same level in the editor and Preview, it works every time.
Even weirder, sometimes it will actually load, but some of the models are missing! And again, if I individually preview, everything works fine.

Why could this be?

Loading a big project takes time and if you need it quick then you should have stable internet source. And if your using the website then i recommned you dowload the app and have the .glb models in a file where it is easily accessible by Gdevelop!

I’m still having this problem, im running the game through the desktop app so its not about my internet.

Running each individual scene loads fine, but if I try to go from scene 2 to 3, it freezes. Its like if I try to load too many things into the game one after another, it just breaks. What can I do?

any way you could share the game. Or add me as a collaborator on the project?
