i had this problem on one of my apps , you should change kivy verision that compatible with kivymd
i use kivymd ver 1.1.1 and use kivy version 2.2.0 or 2.1.0
you should write version of libraries in spec file
like this requirements = python3,kivy==2.1.0,kivymd==1.1.1,requests==2.32.4,sqlite3==2.6.0,jdatetime==5.2.0
