Dolby Atmos Plugin Causing Crash in Unreal Engine on Startup / Opening Project

Hi everyone,

I’m encountering a crash when opening my Unreal Engine project with the Dolby Atmos plugin enabled. The issue occurs in both UE 5.2 and UE 5.4.

I’ve already tried several suggested solutions, including removing and reinstalling the latest Visual C++ Redistributable Packages, but the issue persists.

Strangely, this same project worked fine a few months ago with UE 5.2. Now, when I open it again, it crashes immediately during startup.

Is there any known fix for this issue? Should I reach out directly to Dolby Labs for support on this plugin?

Any help or guidance would be much appreciated.

Below is the crash log summary:

Hello there @maroqand!

Checking around the community, this issue has popped up a few times. There are a few paths to test for this scenario:

  • Checking for Win OS conflicts, as certain MS updates have a tendency to break functionality with Dolby, specially with custom plugins. Please make sure you are working on either Win 10 21H2 or Win 11 22H2, and roll back any recent updates received.

  • Confirm that spatial audio is enabled and running. Please go to Sounds > Playback tab > Properties > Spatial Sound tab > Test both “Off” and “Windows Sonic for Headphones”

  • Next , please make sure you are using the official Dolby Atmos plugin version built for UE 5.4. If necessary, re-download it from GitHub, or the proper portal, and avoid re-enabling the old version.

  • Finally, perform a cache clear on your project, via deleting folders Intermediate, Binaries, and DerivedDataCache from your main directory, then regenerating files, and launching the project again.
