Hello Maqbool Hussain,
There are couple of recommendations I can provide for the "Reset Server Node" issue. Please try the next:

net stop wsusservice
net start wsusservice
- Check the WSUS database integrity with:
wsusutil checkhealth
Additionally, I can recommend the next article for a deeper process of WSUS server cleanup rather than the Cleanup Wizard:
