Epic Launcher

I’m having issues with the Epic launcher. It’s extremely slow and it’s not showing all the UE versions installed. For example 4.19 is gone and it won’t let me reinstall it. Yet if I go into the library there are 4.19 experiences and they do load. I just can’t start anything new and looking forward to installing the new UE4 Studio. Some of the other engine versions like 4.11 are duplicated. I can uninstall them but not remove any of them. I repaired the Epic Launcher think I need to reinstall or repair launcher but don’t want to erase everything else that’s in there. I haven’t found any online solutions yet, wondering if you might have some thoughts before I uninstall and reinstall everything.
