The Surface Pro X is actually an ARM-based device (Microsoft SQ1/SQ2 chipset), not Intel. The Surface Pro with Intel processors is a different product line.
WSA can run Android apps on Windows-on-ARM devices and generally performs better than traditional Android emulators because it uses ARM code directly. However, Microsoft officially discontinued support for WSA in March 2025.
Android Studio Emulator — Works poorly or not at all on ARM.
BlueStacks / LDPlayer / NoxPlayer — These are x86-based and do not support ARM Windows natively. They won't install or run on the Pro X.
Hyper-V with ARM Android image — Technically possible but very experimental and not practical for regular use.
Your realistic options now are:
Use a physical Android device for testing
Remote into an Intel/AMD machine running an emulator
Use cloud-based Android emulators like Genycloud or browser-based solutions
