Folder question mother board not working in 1 year

I received folder question mark exactly in the 12 month of purchase of MacBook . With shutdown it worked twice it happens later in the 13 th month I took it to service centre and they said mother board not working as I did not regularly make updates. Since 20 days passed since warranty over Mac laptop requires replacement of motherboard at my own cost . I fail to understand such mechanical failure with apple product and 20 days warranty over happened because the covid situtation and it appeared small shutdown problem . Did anyone had similar issue ?
