Finally I found the way to fix it:
- For Linux user, delete the folder:
~/.config/snapmaker-luban
, then restart Snapmaker-luban. - For Window 10 user, delete the folder:
C:/User/your_username/AppData/Roaming/snapmaker-luban
then restart Snapmaker-luban.
Maybe delete the whole folder is not neccessary and finding the exact file to delete is better way, but this is the quick and easy fix. Hope this help.
