Alright i'll take a look into it right now, thank you for the screenshot.
Meanwhile, you mentioned that you installed the end user runtime mentioned in the screenshot, but can you try to install the "vc_redist.64x.exe" and "vc_redist.arm64.exe" located in "\Engine\Extras\Redist\en-us"? Those are the game's dependencies, usually when something's missing you will get a message when opening the game telling you to install that, so maybe it could work.
EDIT: Saw there was a new version of the game, downloaded that and the audio works!!!
Firstly don't apologise I feel like an ass constantly being like "um it still doesn't work" T_T
That being said, ran the UE setup and it detected I needed ANOTHER different .NET Framework so I installed that and somehow it STILL doesn't work, starting to think I just have a cursed version of Windows 11
