Got it running after an hour of pain so posting what the errors actually meant in case someone else is stuck. HVCI and Core Isolation both have to be ON, Secure Boot and TPM ON. Mine were all off because I built this thing for a different purpose years ago. If you get a launch failure, check those four before you open a ticket

The TPM one got me. Spent 20 minutes thinking my board was too old. It was just disabled in BIOS

Yeah that's the trap. It's a toggle, not a hardware limit, at least on anything from the last several years

Secure Boot also breaks some people's dual boot setups which is worth knowing before you flip it and lose your Linux partition

Good shout. Back up first if you dual boot

Genuinely more useful than half the guides out there. Bookmarking

Also if you're on a prebuilt, the BIOS is often locked behind an admin password. Ask whoever set it up before you go digging
