It’s not only AMD… I occasionally (every 2-3 hours or something like that) experience the same crashes with an Nvidia GPU. (RTX 3070)
I believe it’s related to something going on between UE 5.X and GPU drivers…
I don’t think it’s related to system stability issues, temperatures, voltages… or nothing like that. Because all the other programs I use are rock solid.
I believe it will eventually end up being fixed by new releases either of Unreal Engine or the drivers.
