Hello,
We are trying to launch a simple UE 4.26 project on Pico Neo 3 using SDK 2.0.2, but the game crashes at startup in CreateSwapChain_OpenGL().
After investigating, it appears that Pxr_Initialize() returns -1 in FPicoXRHMD::Startup(). Later on, Pxr_GetConfigInt(PXR_RENDER_TEXTURE_WIDTH) returns zero which leads to a crash down the line.

What do you think could cause Pxr_Initialize() to fail?

Best regards,
Julien

Edit: here's a simple project that reproduces the issue https://drive.google.com/file/d/1vsWswXaiU3TMRBNwo9U3wuYWgj_S0O96/view?usp=sharing

Dear developer,

Could you please check the Software Version of your device? It is located at Settings-->General-->Software Version.

We recommend you update ROM to the latest version. In the bottom right corner of Settings, click “Check PUI Update” → “Online Update”. After the update, please reboot your device and connect your device to WiFi.

Then try launching your game again. If the game still crashes, please add a comment under this one.
