Downloads from Emby server on libreelec not working

I've paid for a month off emby premiere so I can watch my content while on holiday, but all of the downloads I try fail straight away. The logs end in the following:

[AVHWDeviceContext @ 0x3437480] No VA display found for device: /dev/dri/renderD128.

Device creation failed: -22.

Failed to set value 'vaapi=vad0:/dev/dri/renderD128' for option 'init_hw_device': Invalid argument

Error parsing global options: Invalid argument

Is this something I can fix remotely?

I just updated to v4.3.1.0

Thanks

I tried changing the hardware acceleration to no, but it doesn't seem to have helped. Anything else there that could work?
