I see several previous posting regarding this or a similar issue, but none with an actual fix, so posting again:

After I exit the game and close the launcher by clicking the "X" button in the upper right, the window disappears but the launcher remains on the Windows taskbar. If I left click the icon on the taskbar, nothing happens. If I right click and select "Close Window", nothing happens. If I try to restart the launcher, I get "launcher is already running" error. The *only* way to get the launcher to close is to bring up task manager and "end task". I thought this was a Steam issue, but it happens on my second (non-Steam) account. I thought maybe it was a repair issue, but I am seeing the exact same behavior on my laptop, on both launchers. At first it was intermittent, but for the last week it has been every time.

Hey everyone, we should have this issue resolved in a future update. We run into the same thing, too!
