Hi, i have just this second emailed the logs and windows event viewer logs to support. Thanks, Dan
@Daniel_Underwood
I’m not seeing your email. Did you use the Contact Us method above? Did you use a different one than the one you log into Zwift with?
Hi, i emailed from danu83 at outlook dot com to logs at zwift dot com
Hi, my application crashes when I cross the finish line banner in Tour of Makuri Islands events (happened 3 times in 3 different stages). The rides are not uploaded to Strava, the activities in Zwift lack the last few minutes / kilometers.
I’m Running a Radeon RX 6800 with 16GB of VRAM (which, btw, is under full load in the initial pairing screen and game menu… once the world is loaded it’s all fine).
Windows 10 Pro v. 22H2 build 19045.2251
I have just submitted the crash log.
Tonight: Serpentine 8 in Watopia having the same issue I’m experiencing in Markuri. 15 minutes in and laggy. I quit the ride before Zwift locked-up and crashed. Windows has never crashed when this happens, only Zwift.
Contacted support through the Chat Assistant and uploaded log.
That sounds more like it’s related to this: Zwift Crash "Apple" After screenshot where people have noted the automatic screenshots after completing a route/event or setting a PR etc can cause a crash.
@Steve_Clogg_PACK_LEA has seen the same thing with participants in his group rides I believe.
There are clearly several different issues here.

I wasn’t aware of that, thank you.
But it seems this bug has only affected iOS users except me. I’ll have to check if I can trigger the game to shut down by manually taking screenshots. And I have to review my screenshot folder - there should be some automatic screenshots from those crashed rides (I passed quite a few sprint banners, and Zwift usually takes a screenshot 18:11 into my ride).

I didn’t hear back after this…
Looking at the system logs, mine system appears to be running out of virtual memory when loading Makuri. I have 8gb ram but have just ordered 16gb from Amazon as an experiment to see if it fixes
8GB is plenty for Zwift, you shouldn’t be spending money trying to fix their problems.

Hi. I read 16gb recommended nowadays for Win11 so thought I’d give it a go
I just saw it in this article in the table about half way down: www.cgdirector dot com / how-much-ram-do-you-need/
I was interested the recommended jumped from Win 10 to Win 11 and I don’t know the basis of their recommendation but as I can afford 16gb, thought I’d see if that was the issue for my setup

That article is mostly nonsense. 32GB for gaming is horseplop, and the table saying 16GB for Windows 11 (on what basis? it’s an operating system) doesn’t even marry up with what it says further down. And none of it applies to Zwift anyway - a game which typically uses less than 2GB of RAM when running.
It’s old data now and certainly not recommended, but here’s a test of mine showing Zwift running on a PC with

If you want a good laugh here’s the machine I use for Zwift, It’s my old CAD laptop, a Lenovo W520, i7-2670QM CPU, 32 GB RAM, Quadro 1000M graphics, Windows 10 Pro on a m-sata drive. Tacx Neo1 on Ant+. It gets a Basic profile at a glacial frame rate in Makuri but on the basis that you never miss what you’ve never had I’ve never felt a problem with that.
HOWEVER - I’ve completed all 12 Tour of Makuri group rides with multiple automatic screen grabs taken and it’s never crashed once.

The only way is up. 
With those frame rates it would take you a couple of minutes to notice it had crashed!

Crashed third time in a row on my Mac Studio. It seems to happen at exactly the halfway point of each ride. Crash logs emailed.
How does it know what’s half way in advance of the ride ending?
These are group rides and it crashes half way through the loop. Could be a coincidence but maybe something is happening in the background at the point that causes the crash?
Quick update: It doesn’t seem to be an (auto) screenshot issue. Tried riding an event on Sprinter’s Playground (ZwiftPower - Login), Zwift crashed twice whithin ~5 minutes, then I gave up. Again, shortly after crossing a banner, but not every banner.
Don’t know if this is related to crashing but not less annyoing: All settings are reset after restarting Zwift - volume, resolution etc… Oh, and I really miss camera view #1… This game is so messy right now 
PS: Riding with a friend in London, Zwift actually crashed when taking the automatic screenshot at 18:11 (3 times before I finally quit)
