[Bug] Launcher starts but can't access UE's tab

Hi, after the last launcher patch, my Ue tab does not display anymore. I click on it but it does not activate itself at all (no yellow underline). The other tabs work perfectly (namely: Fortnite, Unreal Tournament, Shadow Complex, Paragon, Modding), when I click on those, they open instantly. Also, I can start UE4 by opening an existing project, but I don’t have access to the tab at all nor the content I purchased in order to add it to a new project, f.e.

Please help !
