Error/Bug crashing Unity on Play

May 11, 2021 - 6:35am #1

Hello,

I see that my problem is known, but it was supposed to be fixed in the last updates. I am using Unity 2019.4.9f1 and Vuforia 9.8 on Windows 10.

I have only one image target and one cube attached to it, I press Play, it works sometimes, I press Play second time, it crashes Unity. Sometimes it will work for a couple of times, sometimes it crashes from the first Play.

I have the webcam profile correctly setup, the privacy is allowed for Unity, I use ony the Windows security defender which it's not blocking Unity.

It is something that is blocking the development process and I cannot find a fix for it. This issue is raised by users since Unity 2018, but is still here.

I am attaching the editor log files, maybe it will help. 

 

Thank you.

So tested the Vuforia Core Examples now with Vuforia 9.8.8 and unity 2019.4.24.f1 - was not able to reproduce a crash but it was  significant slower -> to enter play mode and to go back in Edit mode -it took much more time but was stable -no crash.

Hi,

because your mentioned in your post  that it is a known issue. Do you hav)e any refereces where we can check it (link to the bug report or ticket will be helpful , thanks)

-so I understand your description i

  1. issue occurs in play mode of Unity. Issue is always reproducible when you try to call play mode 
  2. camera setting done according to https://support.microsoft.com/en-us/windows/turn-on-app-permissions-for-your-camera-in-windows-10-87ebc757-1f87-7bbf-84b5-0686afb6ca6b
  3. is the camera the default device camera or is USB .. etc?
  4.  means you use 2019 version with the latest Vuforia version 9.8.8 ?

I have different 2020 installation using the Vuforia 9.8.8 and there is no any issue reproducible - clicking many time the play button ... every thing the play mode is initialized correctly and vuforia was working fine.

 we could check:

- could you reproduce the issue using the Vuforia Core examples -> Vuforia Core examples in the Untiy Asset store , Please, open the scene "3-ImageTargets in the folder Assets>SamplesResources> Scenes    where you have a good example with 4 defined image Targets which could be tracked at the same time.

-is the issue with the lates unity version reproducible e.g. 2020.3.8.f1 - may be is a good idea to test if the problem is still there.

I have the 2019.4.24.f1 and will test the Vuforia Core examples in the Untiy Asset store with vuforia 9.8.8 to see if issue is reproducible . I  wlll let you know if issue is reproducible there.

BR
