I followed the below commands to resolve the issue

To Bring Query Component  status to Online and restart the Crawl.

Please perform the below Steps:

  

Step 1: Stop all the crawls

 

Step 2: PowerShell Command:

 

$ssa =  Get-SPEnterpriseSearchServiceApplication -Identity "Search Service Application"

$queryComponents = $ssa | Get-SPEnterpriseSearchQueryTopology -Active | Get-SPEnterpriseSearchQueryComponent

$component.Recover()

Step 3: Then restart the crawl.
