Packaging error when building for Win64

Hello all,

I’m currently developing an application for the Pico-Vr. The mobile build for the headset works without errors, (have not been able to check it on the device though) When packaging for Win64 it gives an error.

I am using PicoXR and VictoryBP4.27 as third party plugins. The project itself is only BP.
I think the error is visible in the Text below, however that seems to be inside a C++ file.

Much appreciated for your time and attention, let me know if you need more code to look at.

there is a project setting to make the build pkg plugin contents too.

also, occasionally errors can be fixed by deleting your intermediate folder

Hey, thanks for the answer! I have looked into it but have not been able to find a setting to start packaging Plugins with the project, could you point me towards it? I have also tried more builds ranging from containing no Plugins to having the plugins installed and containing some elements from them. They all worked, so it might be something more to do with the contents of the project also.
