D5 Lanucher fails opening

Hi there,

I am trying to open the launcher to install the D5Lite.
The launcher popped up okay for the first time but now it does not run.

I tried these:

Running as administrator
Opening the Launcher from the D5 client
Opening Launcher from start menu (separate from the D5 client)
Restarting and doing all the above again
The Internet is fine
Tried disabling anti-virus/defender, etc.
Latest versions

It always shows like this: a black screen that looks like it is not loading

I had the same issue recently, but uninstalling it once and reinstalling the latest version fixed the problem.
