Can’t get past the join/ ride screen zwift keeps crashing. I have 1 day free trial left

Sorry for the troubles.  I believe your machine is below our minimum specs, so if it has run before and isn’t now it might be worth trying to make sure you close out of as many other programs as you can before you run Zwift.  Might also be worth rebooting the laptop and making sure it’s plugged in rather than running off battery for the best performance.
