Loading assets library starting to be very slow...

Cca month ago (maybe more), the launcher began to be terribly slow. If I open it and look for some things in my library, it reloadings all assets again and again from store (i have cca more than 300 + assets from store (free+paid)). It tooks more than 5 minutes to load all. Is it way how to speed it up? It will be new update related to this?

if I search for something in the library in the search by the entered word, i must wait. Every time when i closed engine and open launcher i have to wait minutes…
