This SharePoint tutorial explains, how to solve sharepoint_config (suspect) error which comes in SharePoint 2019/2016/2013.
Learn how to solve sharepoint config database suspect and sharepoint configuration database suspect issue.
Recently when I tried to open the SharePoint 2019 site, the site did not open. Then when I checked in the SQL Server database, I saw the error in the SharePoint_Config database as sharepoint_config (suspect).

SharePoint_Config (Suspect)
The issue comes if the SharePoint_Config database got corrupted for some reason. Now to solve SharePoint_Config (Suspect), run the below queries in SQL Server. Here I have the SharePoint 2019 farm with SQL Server 2016 installed on the system.
Use Master
EXEC sp_resetstatus 'SharePoint_Config'
ALTER DATABASE SharePoint_Config SET EMERGENCY DBCC checkdb('SharePoint_Config')
ALTER DATABASE SharePoint_Config SET SINGLE_USER WITH ROLLBACK IMMEDIATE
DBCC CheckDB ('SharePoint_Config', REPAIR_ALLOW_DATA_LOSS)
ALTER DATABASE SharePoint_Config SET MULTI_USER
EXEC sp_resetstatus 'SharePoint_Config'
You can see it looks like below:

Once you run the above command, the sharepoint_config (suspect) error will not come and the issue got resolve. You can see the SharePoint_Config database will open correctly.
