Hello Googlepaard,
Have you tried the NVidia Studio Drivers? Those are specifically targeted towards production software (Unreal, Maya, Adobe software and others), the latest Game Ready Drivers aren’t always immediately supported by the Unreal Engine and using them can cause issues. Your graphics card, however, should be fine.
Does this problem also occur in other projects as well or is it this specific project only? You could also take a look into the log files of that Project ([Project]/Saved/Logs & [Project]/Saved/Crashes).
Hope that helps.
Regards,
Vecherka.
