This is an issue with python3 being stricter about distinguishing byte strings and char strings. Here's the diff from my local checkout which fixes it for me:

i am able to compile the robin firmware, But after flashing the new firmware LCD screen is showing Complete even after restart. I am trying to connect via usb no communication.

Marlin fw path: https://github.com/makerbase-mks/MKS-Robin/tree/master/MKS%20Robin/firmware/Marlin2.0-MKS-Robin

What version of MKS-Robin do you have ? What version of LCD do you have? There is a setting to set different version of LCD

@github051 how did you fix this? I am having the same problem with the same board!

Pls download from Marlin official branch and use Atom platformio or Vscode platformio to compile.

Thank you so much! I was previously using Atom and was presented with multiple compiling errors. VSCode was a breeze to use and my board works now!

Glad to hear it is working!! Cheers
