Vuforia crash in Unity 2019.3.3f1 | Engine Developer Portal

Hello,

I've been struggling for 16 hours the past 2 days and I can't get my head around why Vuforia keeps crashing in the editor randomly.

The steps I do are as followed:

Make a new project in Unity 2019.3.3
Install Vuforia via Package Manager
Update Vuforia to 8.6.10 (currently newest)
Add License
Download database and implement
Delete Camera
Create AR Camera
Leave all settings on Default
Create new Image Target
Add sphere as child and move it a bit up
Press Play
Randomly between 1-15 times of pressing play it sometimes decides to crash

It was working when we were using Unity 2018.3.5, but we had to upgrade due to UIWebview being deprecated in iOs soon in April 2020.

I'm using:

Windows 10 Home (64 bit) - Version 1909
Unity 2019.3.3f1 (installed via Unity Hub)
Visual Studio 2019

My hardware specs are:

Intel i7-7700HQ @ 2.80Ghz
16 GB DDR4 Ram
256GB M2 SSD + 1TB HDD
Nvidia GeForce GTX 1070 8GB (NVIDIA GeForce GTX 1070 (GP104M) [ASUS])
NVIDIA Studio Driver 442.19 is installed

I tested this problem on another Desktop and the same problem occurs, I tried switching webcams.

After checking the crash logs, it says that it crashes on VuforiaWrapper.dll

I attached the crash logs, I'm really out of options. Thank you in advance!

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.

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.

Hi,

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

Thank you.

Vuforia Engine Support

I have nothing else running

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

Same error here, I just edit

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.

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.

I also saw that Vuforia

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.

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 have the same problem. It

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 @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.
