[Ginda Wijaya]

Hi all, needs help.

1. All projects written in native kivy are Ok, but some of kivymd crashed

2. All Apk successfully build, both kivy & kivymd

You have I expect found a known issue, the workaround and the explanation are the same as this error message (it also applies to KivyMD 1.1.1)
