What's your computer's hardware? It could be an issue of a GPU and/or CPU that's too old, or you don't have DirectX12 which is what the UE5 version has by default, which can be worked around by making a shortcut for the exe and right clicking it > Properties > and in the text field labeled "Target" you add at the end (without the quotes) "-dx11"None of the last 5 builds never work for me now it crashes a few seconds after startup anyone else have this problem?
If it's not that, then try removing the game's files (backing up CharacterPresets and SandboxSaveGames if you want if you made custom presets or have sandbox saves you want to keep) in C:\Users\your_username\AppData\Local\WildLifeC and starting the game again
