So, I'm trying to do this:
But, when I do this this error pops up:
I've tried a couple of fixes online, including opening the registry editor, restarting windows installer and installing microsoft sql. I even updated my installed microsoft sql local db because i saw that what was installed was 2019 and not 2022. Still couldn't fix it.
Would really appreciate if someone can help me with this. I couldn't continue with what I need to do because I'm stuck trying to do that. It's been days. To whoever helps, thank you so much in advance. Just really desperate to solve this issue. I've exhausted everything, tried searching online and followed their instructions, but still didn't fix my issue. Might be unique to me.

After testing, I can add this MDF correctly. You can check whether there are SQL-related components installed in the installer. as follows:

I found an official solution to this problem:A network-related or instance-specific error occurred while establishing a connection to SQL Server.
Gather information for troubleshooting the error Step 1：Verify that the instance is running Step 2: Verify that the SQL Server Browser service is running Step 3: Verify the server name in the connection string Step 4: Verify the aliases on the client machines Step 5: Verify the firewall configuration Step 6: Verify the enabled protocols on SQL Server Step 7: Test TCP/IP connectivity Step 8: Test local connection Step 9: Test remote connection
Best Regards,
