Ah finally someone else having the same issue as me…
Have you found a solution yet… I managed to get more details from the logs found under the [project name]/saved/logs folder :
[2023.08.29-15.22.19:982][ 0]LogWindows: Failed to load 'D:/Unreal/UE_5.2/Engine/Plugins/Marketplace/MetaHuman/Binaries/Win64/UnrealEditor-MetaHumanMeshTracker.dll' (GetLastError=1114)

[2023.08.29-15.22.19:985][ 0]LogPluginManager: Error: Plugin 'MetaHuman' failed to load because module 'MetaHumanMeshTracker' could not be loaded. There may be an operating system error or the module may not be properly set up.
So it looks to me like it cannot load MSVCP140_ATOMIC_WAIT.dll or one of it’s dependencies… as far as I know this is part of the VC++ redistributable so I tried reinstalling that but no luck so far.
Really desperate to get this sorted
