@ananpeculiar ,

Remove the problematic search service application first, then run following powershell to create a new search service application:

Remember to change the related parameter such as $SearchDatabaseServer,$SearchAppPoolAccount.

#Create Search Service Application  
Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue  
# Specify the Settings for the Search Service Application  
$ServerName = (Get-ChildItem env:computername).value  
$IndexLocation = "C:\Search Index"  
$SearchServiceApplicationName = "Search Service Application"  
$SearchServiceApplicationProxyName = "Search Service Application Proxy"  
$SearchDatabaseServer = "SQL19"  
$SearchServiceApplicationDatabase = "SP2019_Search_Service"  
  
$SearchAppPoolName = "Search Service Application pool"  
$SearchAppPoolAccount = Get-SPManagedAccount "Julie\spfarm"  
  
#Check if Managed account is registered already  
Write-Host -ForegroundColor Yellow "Checking if the Managed Accounts already exists"  
$SearchAppPoolAccount = Get-SPManagedAccount -Identity $SearchAppPoolAccount -ErrorAction SilentlyContinue  
If ($SearchAppPoolAccount -eq $null)  
{  
Write-Host "Please Enter the password for the Service Account..."  
$AppPoolCredentials = Get-Credential $SearchAppPoolAccount  
$SearchAppPoolAccount = New-SPManagedAccount -Credential $AppPoolCredentials  
}  
  
#*** Step 1: Create Application Pool for Search Service Application ****  
#Get the existing Application Pool  
$SearchServiceAppPool = Get-SPServiceApplicationPool -Identity $SearchAppPoolName -ErrorAction SilentlyContinue  
#If Application pool Doesn't exists, Create it  
if (!$SearchServiceAppPool)  
{  
$SearchServiceAppPool = New-SPServiceApplicationPool -Name $SearchAppPoolName -Account $SearchAppPoolAccount  
write-host "Created New Application Pool" -ForegroundColor Green  
}  
  
#*** Step 2: Start Search Service Instances ***  
Start-SPEnterpriseSearchServiceInstance $ServerName -ErrorAction SilentlyContinue  
Start-SPEnterpriseSearchQueryAndSiteSettingsServiceInstance $ServerName -ErrorAction SilentlyContinue  
  
#*** Step 3: Create Search Service Application ****  
# Get the Search Service Application  
$SearchServiceApplication = Get-SPEnterpriseSearchServiceApplication -Identity $SearchServiceApplicationName -ErrorAction SilentlyContinue  
# Create the Search Service Application, If it doesn't exists!  
if(!$SearchServiceApplication)  
{  
$SearchServiceApplication = New-SPEnterpriseSearchServiceApplication -Name $SearchServiceApplicationName -ApplicationPool $SearchServiceAppPool -DatabaseServer $SearchDatabaseServer -DatabaseName $SearchServiceApplicationDatabase  
write-host "Created New Search Service Application" -ForegroundColor Green  
}  
  
#*** Step 4: Create Search Service Application Proxy ****  
#Get the Search Service Application Proxy  
$SearchServiceAppProxy = Get-SPEnterpriseSearchServiceApplicationProxy -Identity $SearchServiceApplicationProxyName -ErrorAction SilentlyContinue  
# Create the Proxy, If it doesn't exists!  
if(!$SearchServiceAppProxy)  
{  
$SearchServiceAppProxy = New-SPEnterpriseSearchServiceApplicationProxy -Name $SearchServiceApplicationProxyName -SearchApplication $SearchServiceApplication  
write-host "Created New Search Service Application Proxy" -ForegroundColor Green  
}  
  
#*** Step 5: Create New Search Topology  
$SearchServiceInstance = Get-SPEnterpriseSearchServiceInstance -Local  
#To Get Search Service Instance on Other Servers: use - $SearchServiceAppSrv1 = Get-SPEnterpriseSearchServiceInstance -Identity "<Server Name>"  
  
# Create New Search Topology  
$SearchTopology = New-SPEnterpriseSearchTopology -SearchApplication $SearchServiceApplication  
  
#*** Step 6: Create Components of Search  
  
New-SPEnterpriseSearchContentProcessingComponent -SearchTopology $SearchTopology -SearchServiceInstance $SearchServiceInstance  
  
New-SPEnterpriseSearchAnalyticsProcessingComponent -SearchTopology $SearchTopology -SearchServiceInstance $SearchServiceInstance  
  
New-SPEnterpriseSearchCrawlComponent -SearchTopology $SearchTopology -SearchServiceInstance $SearchServiceInstance  
  
New-SPEnterpriseSearchAdminComponent -SearchTopology $SearchTopology -SearchServiceInstance $SearchServiceInstance  
  
#Prepare Index Location  
Remove-Item -Recurse -Force -LiteralPath $IndexLocation -ErrorAction SilentlyContinue  
MKDIR -Path $IndexLocation -Force  
  
#Create Index and Query Components  
New-SPEnterpriseSearchIndexComponent -SearchTopology $SearchTopology -SearchServiceInstance $SearchServiceInstance -RootDirectory $IndexLocation  
  
New-SPEnterpriseSearchQueryProcessingComponent -SearchTopology $SearchTopology -SearchServiceInstance $SearchServiceInstance  
  
#*** Step 7: Activate the Toplogy for Search Service ***  
# Or Use: Set-SPEnterpriseSearchTopology -Identity $SearchTopology  
$SearchTopology.Activate()
