I have fixed the crashes on my end for the latest beta build (1.3.0.23) . It seems that the game was crashing specifically in 2560x1440 resolution, which is what the game was defaulting to as that is my monitor's resolution. After managing to lower the resolution the game ran fine with no frame drops or anything for a few minutes of gameplay. Upon trying to switch back to 2560x1440 the game immediately stopped responding again.
My system is running Windows 11, latest update. intel CPU, RTX 3070 graphics card. Hopefully this helps the developer narrow down potential causes.
