Let’s take a look at the description of the process involved concerning each of the listed solutions.

You should try the solutions below, if your Windows 10 PC is not part of a corporate network managed by an IT administrator; otherwise, contact your IT admin as indicated on the prompt.

1] Work or School Account

If your computer is part of a corporate account or a school account, you may not be able to do much. It admins disable some features on purpose, so they cant be changed by you or anything else. This assures computers safety and policy.

However, if you feel you need to change it, get in touch with your IT admin, and get it changed.

2] Ensure you’re logged in as Administrator

First and foremost, make sure you are signed in as an Administrator. If you have multiple accounts created on your system, log in to the administrative account. If you’re logged on to the Windows 10 computer with any other account without admin privileges, you’ll get the Page not available error when opening Windows Security Center.

3] Uninstall 3rd party security software (if applicable)

If you have any third-party security software installed on your Windows 10 PC, you may encounter this issue. In this case, to fix this issue, you’ll have to remove all third-party antivirus programs from your PC using the dedicated AV removal tool to remove all files associated with your antivirus program. Even if you have earlier, via the Programs and Features applet, uninstalled any third-party security software but still getting this error, chances are, that there are residual files from the AV software which is still interfering with the proper functioning of Windows Security Center.

4] Check Group Policy setting

Similar to how an IT admin can block certain things, a PC admin can do the same. However, unlike IT admin, getting it changed here can be easy. For example, if you need to test a website for a malicious attempt, you need to disable or enable Microsoft Defender Exploit Guard.

As your PC admin, to go to the following path and change the policy

Microsoft Defender Antivirus > Microsoft Defender Exploit Guard > Network Protection, and change the policy.

The policy clearly says—

Enable or disable Microsoft Defender Exploit Guard network protection to prevent employees from using any application to access dangerous domain.

Once you are done, the PC admin can always change it back to the default setting.

Similarly, the settings can be changed by the Registry, but you will have to know exactly what should be changed. In the Registry Editor, you need to go to the following path and change accordingly.

HKLM\Software\Policies\Microsoft\Windows Defender\Policy Manager

5] Manually enable Windows Security Center

If for some reason that Windows Security Center has been disabled, you’ll need to manually enable the app.

6] Reset Windows Security Center

This solution requires you to simply reset the Windows Security app and see if that helps.

7] Contact your system administrator

If nothing helps, you may need to contact your system administrator and see if any Group Policy setting has been applied.

Any of these solutions should work for you!
