The epic launcher is making me wait a very long time -upwards of ten mins.- to add anything to a project. Why would this be? It is just gradually getting worse and worse.
what do you mean add? are you importing things into your project or are you adding assets that you bought via the launcher? if your adding packs via the launcher then they need to be downloaded and installed to your project which takes time. in any event whats your pc specs and what is your available performance (cpu available, memory, temps).
either youre computer is not powerful enough to handle unreal or the assets youre trying to import are redonkulously huge
