Zwift crash randomly (because of bluethooth?)

(Simon) #1

Hello Zwift team,

I currently face (again after a longer while) random crashes of the application with a short freeze and afterwards back on the desktop. The system is a windows 10 pc, core i7, 16gb ram, gtx 1050.
I have the slight feeling that other devices like wireless bluetooth headphones are causing this crashes.

System logs are:

Did you fix this as I now have the same issue.

Can you give more info on the system you are using, when it crashes and what trainer interface.

Neo 1 - Win 10, i7 Acer NVIDA 4 gig Graphics.

Interesting Win10 wouldn’t do a reset, I think this was because there was an pending Windows update available, also noticed there was a Windows Defender Update that had also failed.

So Ive turned off completely Windows defender, just rode for 20 mins, no freeze, no crash.

Will do some more testing and update.

Have run same system for 2 years flawlessly then last week this started, random screen freeze for 5 to 10 secs.

What Graphics card do you have? Bluetooth or ant+

It may be that some other program is interrupting Zwift. Look at your task manager to see what other programs is running. I also found the running in Windowed mode give me the best performance. I do use borderless gaming to simulate full screen.

Its an Nvidia 4 Gig, Will try both those things cheers as I do run it full screen. But since I turned defender off its been ok. Fingers crossed.

Lets hope you found the culprit. :grin:

One thing to note Nivida 4gb can be many different Graphic cards, they made the first 4gb GPU in 2008 and trus me that wont run Zwift. LOL

OK, was getting connection refused errors in the zwift log also. So combination of Windows Defender, Dropping the Res and Running it in Windowd Mode in the Settings in Zwift. 10 mile solo, no Freeze! Fingers crossed its sorted. It was doing it every couple of minutes. Thx for the assist.

Are there any news to the original ticket? Windowed mode is not an option. I also run Zwift in elevated mode with admin rights which I thought was solving the problem until it started crashing again…

Why is it not an option?
