Version used: v22.03.3

Error in initialization when found, unable to generate board.json. What is causing this´╝č

After debugging I found that I couldn't load json characters because of jshn.

root@(none):/# jshn -R /etc/board.json 
Illegal instruction
root@(none):/# jshn -r '{"a":"w"}'
Illegal instruction

So, what do I do now
