Menu is greyed out after launch. Overlay is up, but most toggles will not turn on, including ESP.
Windows says Core Isolation is on. What else should I check before I ticket Support?

Grey menu means HVCI / Core Isolation reads on in Windows but off in BIOS. Enable it in firmware and reboot.
A greyed menu with a working overlay is almost always HVCI or Secure Boot off in BIOS. Turn on HVCI, TPM and Secure Boot, reboot, then relaunch in the order on Setup. Cloud DMA needs those on.
Windows definitely says Core Isolation is on though.
That is the exact trap. Windows says on, firmware is off. Check BIOS directly.
Also make sure Secure Boot is actually enabled, not just supported - different line in most BIOS.
Secure Boot was off in BIOS. Enabled it, rebooted, every toggle went live. Thank you.
