V56 and up, Quest Pro Link stability
Hello, I've been developing an app at work for PCVR, we're using Quest Pros and extremely high end PCs with one router that has four WiFi bands, hardware is not an issue here, all new and a bit of an overkill performance-wise. The problems we're having are crashes and stability of tracking when in link, the headsets repeatedly reset and adjust their position as if pressing recenter. We were using spatial anchors before but that can no longer be utilized as they cause our app AND oculus desktop app to crash. We're building on Unreal Engine 5.2 with developer features turned on so we can use hand tracking and anchors on PC. We tested for what could cause the crashes and found out that it is Quest system version, even with the newest plugin in Unreal the app runs smoothly on v55 but still stashes on v56 and v57. Is this a known issue or are we the first to encounter it? Any help with solving the crashes would be appreciated, we had to code our own provisional spatial anchors for now but the instability with link makes them an unviable option.

Gear VR crash issue with unity 5.4.2 p2
Hello, I am developing a simple application in which some data and images gets downloaded from server and gets stored in local storage. Now there are 2 issues - 1) When I start my application for the very first time it runs fine, it do not gets any file from local storage so downloads it from threads. Now when I start the application the second time it gets crashed. If I delete the data from Applications it runs again. 2) After successful run of the application I am on my main scene. Now when I go to another scene and comes back to the main scene it crashes giving a "memory violation" error in logs. I thought that its a Read permission issue so I added those permissions in my manifest and checked if its getting merged in the google project. But then also its happening. Please help as i am under deadlines and literally stuck because of this.
SDK 1.3 ovr_Initialize failure. fffff447 --
Hi, My DK2 runs perfectly with the latest Oculus Home (1.3) and so do the bundled apps. However when I try to compile the SDK 1.3 samples none of them work. The OculusWorldDemo throws up the error message: "ovr_Initialize failure. fffff447". OculusRoomTiny throws up the error "Failed to initialize LibOVR". I cant see a runtime version issue as being the culprit as I seem to have the latest. Please help ! Thanks Sanjit
Bug? If I search for LibOVRRT64_0_8.dll with ProcessExplorer my computer crashes
Download and install ProcessExplorer [1]. Open ProcessExplorer and select Find | Find Handle or DLL... Type in LibOVRRT64_0_8.dll and click Search button. My computer crashes. Any thoughts? As a backstory I was trying to look into why we occasionally see crashes in ovr_Lookup() from this dll with our Unity3d based VR application despite the fact that we are using an HTC Vive.
