FMemoryWriter Crash on importing HDA (UE 4.26)

Hi guys, I’m receiving the following crash error when bringing in a HDA that never used to have any issues importing:

FMemoryWriter does not support data larger than 2GB

I’ve tried a brand new scene and re-exported from Houdini, same issue. I’ve even tried bringing it in as a fbx, same crash/error occurs.

I’ve searched the forums for answers and then deleted all lights and reflection spheres as I know people had issues with light capture map size etc, but this file used to import before, so it can’t be a scale issue?

Any ideas/solutions would be greatly appreciated.

Many Thanks
