In some cases, when you using LDPlayer on your Windows computer and the error code: g_bGuestPoweroff fastpipeapi.cpp:1161/1153 pops up during the loading of the software, you will fail to launch your virtual Android device and it stops at 50%.

the error of g_bGuestPoweroff may also pop up after you’ve enabled the VT. The error is probably caused by the conflicts between the emulator and your Windows Server Virtualization – Hyper-V, Virtual Machine Platform, Windows Sandbox, and Windows Hypervisor Platform. Having those Windows features turned on will prevent LDPlayer from utilizing the VT. Thus, you need to shut them down.
