everyone. I am trying to compile a file in Miktex but it shows this message:
! keyvalue error: "option-unknown"
!
! Unknown option 'vargreek-shape' for package unicode-math.
!
! See the keyvalue documentation for further information.
!
! For immediate help type H <return>.
Can you explain to me what it is and how to fix it? Sorry i am completely new to latex and just found this website.
