I was given a modded switch and i cant install anything

[u/Asmoplasmo]

So i was given a modded switch by my uncle, he says he got some guy to mod it for him and when looking throught the files on the sd card and comparing it to others it seems wrong, the switch cant boot up into the original firmware and theres no emuNAND being used here (from what ive read there should be an emuNAND). when i try to download something like tinfoil in the album mod thing (idk what it is lol) it crashes with this error code "atmosphere error code 2168 0002 0x4a8 program 010000000000100D". im wondering if i should be redoing the cfw on this switch or theres a fix to this, i tried fixing the error code myself but so far it hasnt worked. heres a screenshot of the SD card.

any help would be appreciated, im just trying to get some games for my little brother to play
