I have a Lenovo V15 IIL laptop and was having the much publicised issues with running Zwift on the integrated Intel GPU, in my case Intel UHD. To be specific, the processor in my laptop is an Intel i5-1035G1. However, I do seem to have managed to resolve the issue.
I was having the game-freezing issue. It was very frustrating and really quite traumatic.
Having tried many of the other proposed solutions with no success, I upgraded to Windows 11, uninstalled the display adaptor driver in Device Manager, and used the Intel Driver and Support Assistant to install:
Intel® 6th-10th Gen Processor Graphics - Windows
Release date: December 29, 2022
Since then I no longer have the crashes. I can see from other posts that people have followed this route and had no success, but it has worked for me and if just one person can follow in my wake and rid themselves of the heartbreak of having a pride-worthy effort up a steep climb stopped dead in its tracks by a spinning circle of doom then my work here will have been worthwhile.
Note: if you do upgrade to Windows 11 you cannot use the driver roll-back workaround that others have been successful with so I would strongly recommend trying that first.
