I'm having issues like this as well. Is there any information I can get on how to fix the parsing error?
I got my cheats from cheatslip and the format for the file is txt. I deleted all the cheats I had using "Cheats updater" and using the delete all cheats function. Restarted switch. Started Game, went to cheat file, confirmed "No Cheats" then loaded the cheats via FTP using Filezilla.... still getting the parsing errors
