How to fix Device Security: Standard hardware security not supported on my windows laptop?

Currently, I’m experiencing an issue with Windows Device Security and I would like to ask the Windows Security community for help.

Earlier, I was just checking Windows Security, and when I opened the Device Security section, it showed the message “Standard hardware security not supported.” Previously, everything was working fine and that message did not appear.

In addition, Core Isolation has disappeared when I try to search for it using Windows Search. When I checked App & browser control > Smart App Control, I found that it was turned Off without my knowledge, even though I never changed that setting and it was previously On.

I searched on YouTube and also asked Gemini AI, and they suggested checking Secure Boot and TPM 2.0 to make sure they are enabled. When I checked the BIOS, I could not find any TPM or PPT options. Secure Boot shows as Enabled, but it is greyed out.

However, when I ran Win + R > tpm.msc, it shows that TPM is Enabled and the version is 2.0.

I am very worried and panicking, as I’m afraid my system may have been compromised by an application I downloaded. I would really appreciate any help or advice.

Thank you very much.
