WhatsApp and WhatsApp Beta not starting on latest Insider builds

hey there,

whatsapp not starting on lumia 950. endless loading screen or thrown on home screen.

reinstalling app doesn't help. same applies whatsapp beta.

i had exact same error previous insider build helped, update current build. migration process after update seemed fix app. error occurs again.

i pretty sure installing next update help, isn't available yet.

is there right fix problem except doing hard-reset?

there no "soft" way roll phone earlier build, right?

kind regards
