Support for this version of Windows Server already ended, have a look at:
https://docs.microsoft.com/en-us/troubleshoot/windows-server/windows-server-eos-faq/end-of-support-w...
https://docs.microsoft.com/en-us/lifecycle/products/windows-server-2008-r2
I advise you consider upgrading to the newer version of Windows Server.
Since when this problem started?
Are you facing this issue with other Snap-ins like Services, TPM Management ...?
