OSError: File data/fonts/Roboto-Regular.ttf not found.

This line is the cause of your error. if you're trying to use custom fonts in your kivymd project, you need to have the font file. that is the .ttf file and to use the font without having to put the full directory, you need to register the font with the following lines.

first import label base

from kivy.core.text import LabelBase

then register the font with an easier name to refer to.

if __name__ ==  "__main__":
    LabelBase.register(name="RobotoReg", fn_regular="{full_path_to}/Roboto-Regular.ttf")

you can then use it in your .kv file like so:

MDLabel:
    text: "Text to test if font name works"
    size_hint_x: 1
    pos_hint: {"center_x":.5, "center_y": .5}
    font_name: "RobotoReg"
    font_style: "Caption"
    halign: "center"
