I am unable to start the SQL Server service on my computer.

The service was working fine when I had windows 10 with SQL Server 2017 but after upgrading my computer to windows 11, the service is not getting started. I also tried reinstalling the SQL Server 2017.

Later I uninstalled SQL Server 2017 and installed SQL Server 2019 but still, I am not able to start the service and due to this, I am not able to connect my Management Studio with my database.

The error that I am getting in Event Viewer is:

Faulting application path: C:\Program Files\Microsoft SQL Server\MSSQL15.MSSQLSERVER\MSSQL\Binn\sqlservr.exe
Faulting module path: C:\Program Files\Microsoft SQL Server\MSSQL15.MSSQLSERVER\MSSQL\Binn\sqllang.dll

I have also checked in the "Local System Account" in Log On tab of the SQL Server service.

I have tried reinstalling SQL Server 2017, uninstalling SQL Server 2017 and then installing SQL Server 2019, creating new server with another name, etc. but the neither the service is getting started nor my SSMS is connecting to the database.

Thanks

I installed a new instance of the SQL Server in another drive and now the service has started running.

Note: Only the service for the new instance of the SQL Server (installed in Disk D) is running. The service for the previous instance that was installed in Disk C is not running.
