As far as I can tell from the screenshot, the problem lies with the kmod-tun package.
You need to get this package from the same build run as the firmware image because it must match the kernel version built into the image.
Apparently support for your device has not been integrated into official OpenWrt yet, so these are your options:
get the packages from the same place where you downloaded the image, or
get the source code which was used to build the image, then rebuild the image and packages yourself
