I did both Island outskirts and Country to Coastal and no crashes. Using the 1440p detail level with Mac Pro 5,1 X5690 3.46ghz, 32GB ECC RAM and AMD RX580 on Monterey 12.1. I also took quite a number of screenshots. I use ANT+ connection with Kickr Bike.
My legs nearly crashed, so much slow gravel and dirt everywhere.
