Build crashes using TobiiUnitySDKForDesktop_4.0.4 on Windows10

[Mauricio Partnoy]

Hi! I’ve been having a crashing issue with previously working projects and builds that used an older Unity SDK.

Versions:

-Tobii 4c
-Windows 10 Pro x64
-Unity Editor 2018.3.f1
-Using TobiiUnitySDKForDesktop_4.0.4

The Issue:

-Build crashes seconds after initializing eyetracker
-If eyetracker is disconnected the error does not occur
-The crash can be reproduced inside Unity Editor.
-The crash can be reproduced in example scenes that come with the SDK
-The crash happens after a few seconds if I start a scene with gaze detection, even if the scene is paused or stopped.
-The crash never happens without the eyetracker connected or if a scene with gaze detection is not opened.
-The last time I tested the builds was around 2020. Perhaps on windows 7 or 8, I don’t quite remember.

What I tried:

-Getting Windows Update
-Starting the app as an admin
-Turning off Windows Security
-Deleting tobii_gameintegration_x64.dll
-Using a new copy of tobii_gameintegration_x64.dll

EDIT: The forum is being quite pesky not letting me post the error.log ¬¬
EDIT2: Typo

Issue resolved by updating the Tobii Unity SDK and unity version to 2019.4 to match the newer SDK.

I couldn’t get old builds to work but updating and building again is good enough in my case.
