I’ve got the same problem since updating. Crashes after log-in confirmation & the person on a bike is on the screen with the Zwift music - just goes straight back to Windows desktop screen.

Intel (R) HD Graphics 3000

And please stop blaming our setups all these worked fine until todays update .Very quick to blame old operating systems which worked perfectly until now

Yeah, I had the same thing. A Windows Defender Firewall dialogue box came up saying it had blocked Zwift something something blah blah. Should have taken a screenshot in hindsight.
Doesnt matter we all seen it 
My Windows 10 system is running it just fine too. Perhaps this has to do with integrated graphics cards not being powerful enough for the new world, seems to be a common thread?
I have the same. WIN 7 Pro
Had a good ride today afternoon.
Everything works.
And now after update zwift crash after login

Possibly. Though you don’t load into it (it’s that world 0), perhaps the game is trying to unpack/process assets as soon as you start it up in anticipation of what you will choose.
Seems they had pretty much same problem after last update in october said flicked a switch at hq to sort it .Surely cant be same thing again one month later

Worked this morning OK. Since updating it now crashes immediately after the ‘Login Successful’ screen appears. Windows Firewall message the first time it happened.

I took the update today and Zwift hangs. I get to point of selecting my world and it never gets there.

I have also tried a fresh reinstall and that did not work either.

I have two devices.
win10 laptops have the same problem.
win10 desktop works normally.
Both versions are 1.19.0.
Maybe it’s not an update issue.
I think it’s a ZWIFT server problem as last time.
On devices that haven’t logged in for a day or two, it’s probably works normally.
or
ZWIFT’s servers are denying all connections from devices with specific hardware information.
We are also having exactly the same problem since updating zwift will not launch & get kicked back to the home screen! Also tried unintalling & reinstalling with no change. Looks like looking through this thread that we are not the only ones.
Windows 8.1
HP Pavilion 15 Notebook PC

Zwitft program crash after graphics start and login successful.
Same issue on near new laptop with easily minimum Zwift specs. Windows 10,new game version, latest win update.
Starts loading world and then hangs for 5mins,before finally coming up bluescreen and saying something is wrong with a sad face. And I was bloomin sad too 
Unable to enter event pens on two other devices as well
BUT! Everything worked ok on my full noise gaming PC and 2nd tier gaming PC.
Is that going to be the case now? Having to run thousands of dollars of gaming pc to have the game load then run at 40FPS when it does 200+fps in Ultra in other games???
