At first I though it was related to specific landscape settings and sizes so rebuilt according to the recommended values.
I have a NVidia Volta with 12GB memory so surprised am getting this error when I try and save my scene with a new name or try and resample the landscape size.
Windows 10 , UE 4.25.4

Thanks. Yes I have submitted a proper bug report.
Update - a sort of workaround is to make my landscape invisible in the editor (toggle the eye icon) BEFORE I do a save as. Strange. Wonder if possibly LOD related.
