Sounds like the Pinebook is an ARM based computer. Note that ARM is not a supported CPU architecture for LightBurn.
The simple answer is to say LightBurn won’t work on your laptop.
However, if you want to explore this further I suggest reviewing this Topic where I have a proof-of-concept of LightBurn working on a Raspberry Pi. You may be able to leverage a similar strategy to get LightBurn working on your laptop. I’ll warn you, this is not for the faint of heart.
