Hi @pcaltair@MSSP ,
Which patch did you install in this article: SharePoint 2019 update history? Have you also installed MUI/language patch if there is? Have you installed patches on all APP servers and WFE servers? How about running SharePoint cofiguration wizard using the PowerShell Command:
PSConfig.exe -cmd upgrade -inplace b2b -wait -cmd applicationcontent -install -cmd installfeatures -cmd secureresources -cmd services -install If the error still persists, can you trace more clues or logs about this error?
