PRISM app is a complex and feature-rich application that interacts with various system components, including the operating system (OS), external webcams, and capture cards. Due to this complexity, certain features may not function as expected, or in some cases, the app may crash unexpectedly. These issues can arise for a variety of reasons, such as driver incompatibilities, device connection failures, or system-related conflicts.
Whenever an issue occurs, PRISM displays a corresponding error message to help users identify the problem.
This page provides detailed explanations for each error message, including the possible causes and recommended solutions to resolve the issue effectively.
If none of the solutions below resolve the issue, please contact PRISM support for further troubleshooting:

When using the Application Audio Capture (BETA) source in PRISM, the following notification may appear, and the application may be forcibly terminated.
This error occurs while calling the Windows system API (Windows mmdeviceapi ActivateAudioInterfaceAsync). When this API is invoked, it automatically creates an asynchronous thread, which then attempts to execute a callback function. However, an error occurs during this process, causing instability. Since the thread-related data is managed by Windows, PRISM cannot directly control or resolve the issue. As a result, the exact cause of the error is difficult to determine.
The issue is likely due to instability within the Windows API, meaning a Windows update may be required to fully resolve it.
Update your Windows system.
Open Windows Search, type Check for updates, press Enter.
Install any available updates from the Windows Update screen.
Try running the Application Audio Capture source again.
If PRISM detects an error with this source, it will automatically delete it.
Manually delete the laboratory-win-capture-audio.dll file and re-enable the source.
PRISM attempts to delete problematic plugins automatically, but permission issues may prevent automatic removal.
In this case, manually delete the file by following these steps:
Right-click on the PRISM app.
Select Open file location.
Search for laboratory-win-capture-audio.dll.
Right-click the file and select Delete.
If the problem persists, consider waiting for Microsoft to release a fix for this API issue.

While using the Video Capture Device, PRISM Lens, or PRISM Mobile source in the PRISM app, the following error message may appear, causing the app to forcibly terminate.
Depending on the source used, PRISM may either crash or fail to display the camera feed properly:
If using the Video Capture Device source, PRISM may force quit.
If using the PRISM Lens source, the camera feed may not appear.
This error occurs when PRISM attempts to retrieve the video feed and device information from a connected camera-related capture device (USB camera, capture card, etc.).
Possible causes include:
Unstable connection between the camera device and the PC.
Faulty or outdated drivers for the camera device installed in Windows.
Incompatibility between the device, Windows, or PRISM.
Check the Connection Between the Camera Device and PC
Ensure that the device is properly connected to the correct port.
