Whole gui works fine even download repo but genrate error

    You can't create widgets in other threads than the main thread . To open the message box, you could use a signal to emit the message that you want displayed and connect this to some slot (could be a method in `mainwin`) to open the message box in the main thread. – Heike May 16 '21 at 09:21
  • @Heike I did exactly same earlier but as I am cloning repository , it takes little time and till that time Gui freezes , shows two options force quit or wait – Adnan Sheikh May 16 '21 at 16:09
