When I tried to open my UE5.0 EA project with UE5 Preview this happens. Just wanting to make sure it’s not an isolated case so I can go back to patiently waiting for an integration update 😀

Update:  
I tried to strictly open the project from UE launcher with 5.0 preview and the above error didn’t appear, and I was able to open the project **if Fmod is deleted**.

If I added Fmod back in plugin folder and build everything again (after deleting binaries, intermediate, saved), it will fail to build with the following log.

```auto

Apologies for the delayed response, [GitHub - fmod/fmod-for-unreal at 2.02-UE5.00](https://github.com/fmod/fmod-for-unreal/tree/2.02-UE5.00) and the download from our website have both been updated to support UE5 Preview.
