Zwiftapp.exe crashed after latest Windows10-Update

After 40mins of riding as a Sweeper in a group-ride, zwiftapp.exe crashed without further notice - no specific hints in zwiftlog.txt, but an application error in the Windows Logfile - any idea?

If you were part of a group ride team I guess you were typing quite a lot?

Do you have a Kyocera Printer installed on this machine?
Install win Update KB5001649 or deinstall KB5000808.
With the March Update KB5000808 (results in version x.868) you get all sorts of weird problems.

Also your version of ntdll.dll doesn’t match with your OS info.

Nvidia driver is not up to date.

Doesn’t matter. I haven’t even bothered manually installing it on builds for ages now. I think this is the same text character issue others have reported.

Hi Dave, what kind of “text character issue” do you mean? I didn’t find any hint…

Hi Ben,

not even a single printer-driver is installed…

Sure, I’ve typed a lot - nearly every minute - so, what kind of text character issue are you talking about? I didn’t hear about that…

There’s a repeatable bug with the latest update where typing too many characters crashes the game to desktop. Obviously a major problem.

You can probably repeat it, as I did, in a free ride. Open chat pressing “M” then hold down a key on the keyboard while it maxes the character limit and beyond and 50-50 it will crash to desktop. Doesn’t seem to be affecting chat in the companion app, apparently.

Hi Chaps, thanks a lot for all the hints - I was able to reproduce the problem as described: I’ve used a copy-paste text with 124 chars and zwift crashed - but not on companion app… the big question here is: is it dependent on ONE message with too many characters or does zwift summarize the chars of many messages?

Good point, I am just staying away from the keyboard full stop! Especially once I have covered more than a few kms…

Apparently an update has been applied that fixes the chat bug crash. I have just tried to recreate it after the update and it seems to have worked :+1:

wow - I’ll leading a big ride today - great news! I can chat as if there would be no tomorrow… :wink:

Just note Eric’s aside as a ride leader: Zwift Update Version 1.11.0 (65416) Released - Zwift Insider

  • "Fixed a crash when Zwifters would send a very long chat message in game.
    Word is there are still problems with ride leaders using AutoHotKey to send messages – if the keystroke rate is too fast, it crashes the Zwift game."

Aaaaaaaagh - just hit this new bug yesterday - no joke. I typed too fast (I’m a typewriter-veteran…) and Zwift crashed again. This is so fXXX annoying… it happend during a group-ride as leader 15 minutes before end - left over 400 riders “leaderless”… This is far away from having fun…

How annoying! At least it’s one you can avoid a little easier but no less frustrating for yesterday’s ride.

I wonder when the time comes (or perhaps it’s already being worked on in parallel?) that Zwift rebuilds things from the ground up to make the base code less messy and largely eliminate these type of widespread issues? As much as I love it, there really does seem to be some fundamental flaws in the way it’s been built.

Well said!
