Windows 10: 2 Windows security health on startup

So recently i was having problems with Wacatac virus on my pc. It wouldn't stop showing up on windows defender and I couldn't get rid of it. It also wasn't on AppData folder but rather it showed pid: "some id" and ProcessStart: "some id". The id's changed every day. So I went to see startup on my manager and I found 2 random chineese letters apps on the bottom of the list. Later on I found an app on my AppData/Roaming folder that was suspiciously named wssdadadadsds.exe along with some more suspicious stuff. When I went into it's properties it said used 40 minutes ago. I shift deleted both of

We appreciate your time responding back to us. At this point, we would suggest that you access the built-in Administrator account to and check if you would be able to perform a Health Check from it. Here are the steps on how to enable the built-in Administrator

  Enter.

Health & Performance Report Not Available on 2 user accounts except the administrator's account in the laptop has Health Report

Thanks Jaune . I performed the first 3 steps in my built-in administrator account & did get the Health Report back for this account. However I did not perform the second set of 3steps as I do not understand it & have fear that it would remove the newly
emerged Health Report. I tried perform the first 3 steps on my second administrator account which did bring the Health Report, on finding later that Health Report is no longer available on my built-in admin. account

Despite this, this is the best advice so far as all other answers like performing a clean boot, starting in a safe mode did not work for me at all.

Jaune, will you please help me further to fix the "add new user account" problem. None of the admin account will respond to my click on add account. I want to remove the second admin account where no Health report is available, hopefully to have the issue
fixed when I add it back on. Is there a maximum no. of user accounts in the laptop? I want to see that I can add to replace user account removed due to problematic performance
