nDisplay Crash in DisplayClusterDeviceBase.cpp

I created a nDisplay test project with the attached cfg file.[Link Removed]

^{(PS: a Chinese client also reported this in a UDN thread https://udn.unrealengine.com/questions/598251/%E5%85%B3%E4%BA%8E4253-ndisplay%E8%BF%90%E8%A1%8C%E5%B4%A9%E6%BA%83%E7%9A%84%E7%9B%B8%E5%85%B3%E9%97%AE%E9%A2%98.html#)}

Before 4.25.3, it works correctly, after upgrade to 4.25.3, after lauching the nDisplay project via nDisplay Launcher, it will firstly display the viewport and then after 1 second, it crashed and reported:
