Sorry confused, the title says Scene Collection, but you mention changing scenes. Is it when you change collections, or when you change scenes? There might be something wrong or corrupted in the collection you are switching to. Try creating a NEW blank collection, and see if you can switch in and out of that with the good collection you are using as base, if so, then you might have to recreate that entire collection, especially if you can no longer access it. If you can access it somehow, then you can try to duplicate it or export it and reimport it.
