I have a project where a VuMark scan triggers a timeline canvas to appear in HoloLens, using Unity 2022.3.25f1, MRTK3, and Microsoft Visual Studio 2022. The Unity project is built on UWP and operates within HoloLens. Additionally, I’m utilizing a UR10e robot on a virtual machine. I established a connection between the HoloLens and the UR robot. I’ve successfully connected to the robot from Node-RED to send messages and control it and established communication from the robot and Node-RED back to the HoloLens. In play mode, it works well. Previously, I could run it on HoloLens, but after a while, without any changes, I received an error: “The certificate could not be opened. SATestCertificate.pfx. The specified network password is incorrect.” I tried to fix it by creating a new SATestCertificate in PowerShell and adding it to the player settings. Now the project builds successfully without any errors, but when it is loaded on HoloLens, it shows nothing or sometimes a white window with a cross at the center. Does anyone know what the issue is and how to solve it?
