Still waiting for an answer...
This Is only because Last Night I Reset Wp Form setting to default and was trying to see if this fixed the problem,
I myself changed forum to Community But again this did not solve my problem in google search console. and it is still showing in site maps that "0" URL discovered.?
Yes, it Worked, So The answer for anyone looking for google search index problem lies in the fact that we need to use community in url or use default wp-foro settings, I just reset the forum urls and google is discovering URLs now.
