Hi Mcorota,

Yes, it also crashes with the new 9.0.12 version, using Unity 2019.3.3 at the VuforiaWrapper.dll again. Just making simple ImageTarget scans as well, first time Play after starting Editor seems to work, but it almost always crashes on the 2nd time pressing Play.

HI @mcotora

My unity version is 2019.3.2f , and the first time I met this problem was in vuforia 8.5.9,then I upgraded the version to 9.0.12,but there are still problems,random crash...

The main functions I use are "ImageTarget"

I try to identify the problem myself,Then I'm sure it's during initialization,Only when i don't execute " VuforiaRuntime.Instance.InitVuforia();",It can never break down...

And there's another thing that I'm sure "vuforiawrapper.dll" led to the crash,it from crash logs

I hope it can be solved as soon as possible. Now it has affected normal work

thanks

Hi @smann,

Could you please confirm on which version you are encountering the issue?

Thank you.

Vuforia Engine Support

I am experiencing it as well. This is disappointing as it's killing my productivity.

Hi @rudolfwm and @cuiyh1993

It seems that with the new 9.0.12 version, the issue is not reproducible.

Could you please confirm that you are also encountering this issue with 9.0.12?

Thank you.

I have the same problem. It will crash randomly and lead to bad development. I want to know when I can fix it. Please do it as soon as possible,thanks thanks thanks

Hi,

We are in the process of releasing the new version, all information including release notes will be available shortly on our website.

Unfortunately the issue is not fixed in 9.0.12 but should come in the next release.

I will update the thread once I have new information.

Thank you.

I also saw that Vuforia released a new version: 9.0.12, but I cannot find any changelog online or within the project after updating.

Hopefully it has been fixed in this version, I shall await your reply and test in the meantime.

I have nothing else running besides Windows Defender, but I added the following Exclusions just in case.

Hi @VladVlad1 & @rudolfwm

I was able to reproduce the issue and informed the dev team.

I have tried to reproduce on Windows and also on Mac this seems to be reproducible only on Windows.

As soon as I have new info, I will update the thread.

Thank you.

Hi,

Do you have any antivirus running besides Windows Defender? If yes, could you please add Unity and Unity project as exceptions?

Thank you.

Same error here, I just edit one string in my scripts - hit play and it crashes with like 50% chance. Logfile also contains VuforiaWrapper.dll violation error.

The crashes occur randomly, but always when I enter Playmode. Sometimes it works after pressing 5/10x play and then crashes, other times it crashes after restarting Unity and pressing play 2x. It's completely random, but always the VuforiaWrapper.dll.

Vuforia itself works, I have permissions on and the scans are working while working in the editor. But I can't have my colleagues get random crashes when we're in production.

Hi,

Thank you for the detailed post.

Does this happen always when you enter Playmode?

Could you please check Windows Settings/Privacy/Camera and set "Allow apps to access your camera" to "on?

Thank you.
