Launcher stays empty after launching.

[pulli23]

After downloading the launcher I get an empty screen, the background shows but the command window as well as the buttons stay "empty". I am using java version 8 update 241. (1.8.0_241-b7)

(ps: how do I link to imgur to show the image of what is happening?)
