Hi @Basim Alvi ,

Based on my research, you can do some troubleshooting:

Make sure all SharePoint services are started under Services.msc.
Go to Services.msc.

Go to Internet Information Services(IIS) Manager.
If the error occurs when accessing the Central Administration site, the SharePoint admin center v4 application pool may be stopped and needs to be started.If the error occurs when accessing the SharePoint site, the SharePoint – 80 application pool may have been stopped and needs to be started.
For this, select the correct application pool, click Start. Reboot if already started.

If the necessary application pools are started and the error persists, then you should check the group membership of the group IIS_IUSRS and the application pool account in Local Group Policy (visible in IIS Manager).
Check the group membership of the group "IIS_IUSRS"
Go to IIS Manager, note the account of the application pool in question in the identity column.

Go to lusrmgr.msc, Open Local Users and Groups and the group "IIS_IUSRS".The application pool account must be a member of this group.

Check the application pool account in Local Group Policy.
Go to gpedit.msc. Open Local Group Policy Editor.
Open the following items:
Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment.
Verify that the IIS_IUSRS group is included in the following policy:
"Log on as batch job" and "Impersonate client after authentication"

Check ULS log file to check if there are any clues about this issue. The path of ULS log files are C:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\LOGS.
There is a blog about how to check ULS log for your reference:
