I NEED HELP

[bugfly66]

'On first launch, you will be prompted to generate a fontmap. ' didn't appear.
When I use ’Regenerate Fontmap‘ :

Error: J:\App\lite/data/plugins\fallbackfonts/init.lua:297: attempt to index upvalue 'fontmap' (a nil value)

It seemed that I don't understand how to use this plugin.
The fallbackfonts folder:

looks very wrong. Can you share your config?

It's default. I didn't change it
