+You may need to disable virtualisation-based security (VBS, or "Core isolation" in Windows Security):
+
+1.  Open Windows Security (by searching for it, or from `Settings` > `Update & security` > `Windows Security`).
+2.  Go to `Device security` > `Core isolation`, then toggle `Memory integrity` off.
