Tomodachi life was working, now fatal error

Issue
i started tomodashi life on citra, then it said mii data is missing, so i addet the .nand file thing, and the game started and worked totally fine.
Then i was just scrolling through some safe .txt fales, and now, a fatal error accours right away.
I allready extracted a new .3ds file from the .rar file and complettely removed citra and all of its foalders and downloaded and installed it again, the same way like i did this morning, but this time it wont work

iam not really a technical guy, but i hope you can understand it and help me
