UE freezes when loading assets

So I know this issue has been asked a lot, but I’m new to UE and the current situation just feels absurd to me, I understand that assets sometimes takes long time to load, and thats totally fine, but why when an asset is being loaded everything have to freeze? Why does it have to affect and freeze my explorer as well? It makes no sense to me. Why not just add a loading bar to know where the current loading is, and why not maybe load it ‘on the side’ from another instance or something similar so you’ll be able to work meanwhile when loading an asset?

On another note, is it possible to somehow preload the assets? Just let it load everything at night or anything similar?
Any other solutions will be much appreciated.

try loading assets one at a time because each asset needs to be compiled and it takes a couple seconds to minutes , loading too many assets will make it freeze or crash , me for example i try to retarget several animations to one skeleton and it crashed

I am loading one asset at a time, of course some of them are bigger, some of them are smaller, but I still can’t understand why it works that way(again, not talking about the time, but mostly about the whole PC freezing).

Anyone…?
