Custom Java app, does not show startup splash screen on some devices?

I have a Java app, called Infra12. It is not for sale so wont be in common use. It is designed to interrogate industrial equipment, but the supplier of the software has gone into administration, and they only supplied it to customers who bought industrial equipment from them - one of them being us. This app contains JRE within it, so it should run without JRE being installed on the machines themselves - none of the devices I have tested it on have JRE installed.

I have a problem with this app, which I cannot solve. When I run it, on some machines it will show the startup splash screen, thereby letting me enter the product key so I can enable it. However, on other machines this startup splash screen does not show.

Machines I have tested this on where it works:

HP Prodesk 400 G5 PC, Win 10 Pro 1803 17134.407, x64, i5-8500 3.0GHz, 16GB RAM, Intel UHD Graphics 630 1GB, 1920x1080

Xiaomi Mi 13 Air laptop, Win 10 Pro 1809 17763.194, x64, i5-6200u 2.3GHz, 8GB RAM, Intel HD Graphics 520 1GB / Nvidia Geforce 940MX 1GB, 1920x1080

Acer Revo One RL85 PC, Win 7 Pro 7601 6.1.7601, x86, Celeron 2957u 1.4GHz, 4GB RAM, Intel HD Graphics, 1600x900

Machines I have tested this on where it doesnt work:

HP Envyx360 laptop, Win 10 Home 1803 17134.407, x64, i7-7500u 2.7GHz, 8GB RAM, Intel HD Graphics 620 1GB / Nvidia Geforce MX 940MX 1GB, 1920x1080

Surface Pro 4 DESKTOP-LR0D2QT laptop, Win 10 Pro 1809 17763.194, x64, i7-6650u 2.2GHz, 8GB RAM, Intel Iris 540 1GB, 1920x1080

Dell Vostro 5468 laptop, Win 10 Pro 1809 17763.194, x64, i5-7200u 2.5GHz, 8GB RAM, Intel HD Graphics 620 1GB, 1366x768

I have tried to run it using CMD prompt on the non working machines, and have managed to get an error log generated by the app, which I cannot decipher:
