Like @Matt_Wheeler described previously (see link below), I experienced an unexpected Zwift Crash today right after the finish of an ECRO race. It seems Matt and a few others continue to have this problem, so I’m creating this thread.
To Zwift, please fix this bug. 
To other racers who experience this, here are a few notes from Matt:
- After a couple min, your activity should show in Companion and be titled “Watopia” or something similar (may depend on the event route)
- That said, it still likely breaks your *.fit file / messes with new route completion and PRs
- Use your Zwift Feed to get 95% of the file
- Apple TV doesn’t seem to have any issues
- To help resolve this, try sending support@zwift.com your:
- Device type (e.g. PC)
- Zwift video resolution in settings (e.g. Ultra)
- Log file snippet showing event completion line (instructions below)

This issue has survived 3 version updates for me.
My working guess is that we are part of a small test group related to graphics and it’s bugged. Only people who actively do events will realise there is an issue.
My ticket was escalated to “level 3” and is apparently with engineering. I’ve had no updates.

To future readers, in my Zwift Support thread, they requested I check the following:
- Please ensure you have a strong and stable internet connection.
- Restart your device before riding to clear background processes and improve performance.
- Close any unnecessary apps running in the background that could interfere with the game or cause connectivity problems.
- Logging out of Zwift and back in can also help.
- If possible, try switching to a different network or using a mobile hotspot.
- Please make sure that Zwift, your operating system, and your graphics drivers are fully up-to-date.
- You can check for GPU driver updates directly on the manufacturer’s website (AMD, Intel, or NVIDIA).
- Make sure the firmware of your Zwift Play is up-to-date.
- You can update it via the Companion app.
- We also recommend resetting your game preferences.
- After that, please re-pair all your devices directly via Bluetooth in the Zwift app.
The one thing on here that I needed to do was go to the Intel and NVIDIA sites to manually update my drivers. The built-in Windows Update and Device Manager’s “Search automatically for drivers” said everything was up-to-date, when it wasn’t.
TBC if this will solve the issue.
Is this a laptop that has both an Nvidia GPU and Intel integrated graphics? If that’s what you have, only one of them will be used for Zwift at any given time. In Windows Display settings for Zwift, the default will be “Let Windows Decide” but you can force it onto one or the other as you wish. If you upload a log file to zwiftalizer.com, it will tell you which GPU was in use for any given Zwift session, so you could check if either one is more stable.
In my experience, updating the drivers for Intel integrated graphics often improves stability. Latest drivers for Nvidia GPUs usually doesn’t help anything, and the Nvidia driver that comes from Microsoft is usually stable. Nothing wrong with trying a different one of course.
There are so many various reasons for game crashes that I couldn’t begin to guess if you and Matt are facing the same problem. The recommendations you got from support are just the boilerplate first things to try, which do fix many problems but I’m guessing Matt has progressed way beyond that if his case was already escalated to their best support people.

Yep, you guessed it, @Paul_Southworth. My laptop has what you said. After checking Zwiftalizer, it looks like Zwift was using my NVIDIA GeForce RTX 3050 Laptop GPU. Good background, thank you.
On a semi-related note, I raced another ECRO race - before this post and all the driver updates - but at a lower game resolution and didn’t have a crash at the finish.
Have you also disabled the video screenshots setting in Zwift? That has sometimes resolved finish line crashes. It’s only available for some CPUs and for some it’s enabled by default, for others disabled by default.
Yep! I did that several months ago. Someone in my club tipped me off to that and it helped fixed frame rate issues that I was having.
For confirmation. I’m on a PC with updated AMD graphics and have sent crash logs to zwift that they were unable to diagnose from. I have done 4 complete reinstalls.
I have crashed at the end of 28/28 races.
I have been fine on 3 races when using my apple tv.
I have been fine on 3 races when using a trial account on my pc.

Had something slightly different happen today. 40 sec before a Ladder League race start, my computer entered what appeared to be a sleep mode despite being plugged in, no other apps running, etc. After a few minutes, I was able to get my computer back on and then race. After about 20 min of racing, the game kept trying to make me quit the race (like hitting Esc a few times). It happened probably 5-6x. Here’s a zwiftalizer link. You can see when the computer goes to sleep around 7:30P ET.
My computer was forced into a sleep mode again for the past two days. Both days it happened some time after I completed a workout and I was running it in 4K UHD. I’m going to try 1080p to see if that helps.
June 6: Zwiftalizer 2.0 (was able to keep running Zwift after I got my PC to turn back on)
June 7: Zwiftalizer 2.0 (Zwift quit shortly after the incident and I had to restart the app)
This just happened to me for the first time in years, right after crossing the finish in a Glasgow Circuit Advanced Race, moments ago. You were actually in the race with me, Matt.
Hopefully Zwift can resolve this quickly. I’m on Windows 11, Ryzen 7 3700x processor, NVIDIA RTX 2060 Super.
