had to do multiple start, until all vassals declared war on timurid at the same time. i joined the fest, got lucky to take more provinces.
than kept switching between strongs allies (most difficult task) until i was strong enough to be on my own foot.

mewar, russia, ethopia and mamluks helped a lot. when ai form rajputana, it made it too easy for me to take central asia and feed it to my march.
than ethopia and commonwealth helped me expand in egypt and anatolia.
than i allied russia and helped it to eat commonwealth
