Zwift does not start on windows

Thanks for the log info. There’s not a lot to go on there - the only thing that looks really odd to me is the “window size 0x0”, i.e. a zero-size display?

I’m not technical enough to know what might be causing that but it seems like a few other people have had a similar issue to you previously and got the same message in logs: Software problem with Windows 10

It looks like a full reinstall (and deleting Documents folder Zwift contents) potentially fixed it for one of them? But I’ll be honest I am out of my depth here, I’m not technical enough to know how to help you further on this. Hopefully someone with more technical knowledge will swing by and help further if the above link doesn’t help!
