Help? Virtual keyboard driver is outdated error

[GlynGreen]

I've used Karabiner for a year and half since getting my first Macbook - I have to have backspace and page up and down keys as I use all these very regularly and I find it idiotic that Apple missed these off their premium laptop.

It worked great till recently but now Karabiner has stopped working. There's an error message that tells me MacOS restart is required and that the virtual keyboard and mouse driver is outdated.

I've restarted multiple times and it's not helped. Looking at the log it says Karabiner expects "VirtualHIDDevice-Daemon expected 10800, actual dext: 10700." MacOS and Karabiner tells me I don't have any updates.

I have the free version of AVG antivirus on my Mac if it might be relevent. I've been running this fine for months with Karabiner working well with it though.

Anyone have any suggestions how to fix this please?
