I looked everywhere but I could not find an answer, so here I am.

I tried to run Sitecore's broken link report (in Control Panel > Reports > Scan the database for broken links) but got the below message. Have any of you encountered this?

An error occured

    <command name="system:brokenlinks" type="Sitecore.Shell.Framework.Commands.System.BrokenLinks,Sitecore.Kernel"/> this command is responible to create report, If you didn't find a solution then you can debug this. Sep 24 '20 at 15:16
  • The weirdest thing is that I cannot reproduce this locally. It happens only on prod. It works on UAT as well as it works on my dev machine.

I encountered same issue while removing Roles from RoleManger, after that unicorn sync stopped working. I found the proper explanation in the below link. Not sure if it will resolve your problem but it fixed the issue for me.
