It depends on where you copied this Sunton folder. Make sure you deleted the ‘Sunton (ESP-IDF 5)’ folder from ‘boards’ folder in both the program’s installation folder and the ‘Documents\SquareLine\boards’ folder.
Thanks, it helped. I deleted board from the programs folder and documents folder. As I understand, it is enough to put board only in the ‘Documents\SquareLine\boards’ folder.
