Here the blocks
Whitout any action ? Try to disable one animation at time , so you are sure that they work properly.
Maybe Lottie with animation
i removed the entire block section about animations
is still not working
All animations? Can be some extension bugged too or some wrong settings . Have you component like Firebase ? Appears some error message? A Lottie file bugged
To find out, why you get a runtime error, use logcat
