Most drivers have seen their insurance prices hiked this year, with companies blaming an increase in claims following the pandemic, as well as rising parts prices and parts supply issues. Toyota Auris Hybrids such as yours are particularly prone to catalytic converter theft, which might explain why your current insurer refuses to insure your car. We'd recommend replacing your Auris with a small automatic city car such as a Kia Picanto or Hyundai i10. Also consider small electric cars such as the Peugeot e-208 or Fiat 500 Electric - but do shop around for quotes first.
