When I press G(for game mode) my landscape vanishes

When I press G for game mode my landscape disappears. I saw people having this issue with 4.16 and I tried whatever seemed to solve their issue but it doesn’t fix my issue. I should mention the engine crashed and that message that appears whenever the engine crashes came up. Any way to fix this since my landscape needs to be visible in game mode?

Thanks

I had trouble with this too. It seems when i altered material functions in my landscape material would cause the whole landscape to vanish in game mode. Selecting the landscape, and going into the landscape editor and resampling it seems to fix it
