ASG 2018 manual available?

I'm not sure - but perhaps you can check if you have installed all patches for the SQL (Express) instance - the TLS 1.2 should be used automatically when using the newest .NET - and the app uses the newest .NET framework! So it should be the SQL express that comes with this error

If you have an SQL cluster available you should try to use it instead of the SQL Express to see if it still happens or not
