Epic game Launcher installed but can't load update?

After resetting my pc, i want to download fortnite again, but after installing it, the launcher now tells me "please wait while we start your update" and it won't go away. What helps?

Delete the launcher again and try again, if it has not fixed it, log in again

I've done it many times, but it doesn't work

Try starting the epic games launcher as an administrator, that could help

The epic launcher killed in task manager and restarted? Sometimes it hangs up.

Unfortunately doesn't help either

Same problem can help us nothing works

Have the same do not know why
