The update to version 5.4.1 seems to have fixed my problem. I didn't change anything on my system.
I've just tried to install 64-bit gnuplot and got the same error. It's with the latest gp528-win64-mingw.exe from sourceforge, I'm on a fresh Windows 10 installation, version 1909. Restarting and installing with admin permission didn't solve the problem. When opening gnuplot from the startmenu, I can see the window for like 2 seconds before it closes itself. Same with the console version. Edit: Added the event viewer log if that helps by any chance.
