Enter your BIOS/UEFI and make sure:
Secure Boot is Enabled
TPM 2.0 is Enabled (sometimes called "PTT" on Intel, "fTPM" on AMD)
Double-check Core Isolation / Memory Integrity
Powershell command also use this again: bcdedit /set hypervisorlaunchtype off
Then go to Windows Features (OptionalFeatures.exe) and turn OFF:
Hyper-V
Windows Hypervisor Platform
Virtual Machine Platform
Windows Subsystem for Linux
If above doesn’t fix it, check BIOS:
Intel Virtualization (VT-x / VT-d) Try toggling OFF and test
Sometimes Vanguard conflicts if VT-d is enabled :kappapride:

First of all, thank you for your response. My PC doesn’t support TPM 2.0, and everything was running smoothly until I changed the BIOS settings from LEGACY + UEFI to UEFI and enabled SECURE BOOT. Since then, I’ve been getting the error, even though I reset everything back to the original settings.
Strangely, I also can’t enable HVCI anymore; it keeps turning off after every restart.
