Dell Inspiron 5370 Caps Lock weird issue

Hi there, I've installed Mojave 10.14.5 using Vanilla method on my Inspiron 5370. All works perfectly (audio, brightness, volume control keys) but there's a little issue that I can't fix. If I spam the Caps Lock key after 2 times the whole system freezes and I'm forced to reboot. Is there any fix? I'm using Acidanthera VoodooPS2 (latest version on GitHub) and ApplePS2SmartTouchpad (for fixing the scroll issue using the trackpad).

Thanks
