We’re using FMOD plugins with version 2.03.06 in a C++ Unreal Engine project.

Everything works perfectly in the editor, but the Desktop packaged build crashes immediately when I run it. The crash occurs as soon as the executable is launched, and it appears to be related to FMOD plugins.

Here’s a snippet from the crash log that points to FMOD as the main cause:

We’ve followed the documentation to set up the plugins correctly, and there are no errors or warnings during the development in the editor:

Additionally, I’ve tried recompiling the plugins according to the guide here:  
[https://www.fmod.com/docs/2.02/unreal/user-guide.html#compiling-the-plugin-optional](https://www.fmod.com/docs/2.02/unreal/user-guide.html#compiling-the-plugin-optional)  
but the issue persists in the packaged build.

Thanks in advance for any help or suggestions!

I’m not able to reproduce this so far on my side.

Are you able to provide the full output log? You can upload it your [FMOD Profile](https://www.fmod.com/profile#uploads) if you prefer.  
Can you confirm that the FMOD Plugin files are inside the built package?

Thanks for reply, the issue has been solved by fixing the incorrect solution generation that caused by incorrect uprojectdir setup in Unreal Engine 5, which eventually lead to the a failed plugin compilation.
