Neo4j desktop times out even though database does start up

I have a relatively large database that takes a long time to start up (in Neo4j Desktop), the first time. During this time, while the database is still starting up, neo4j desktop throws a timeout error message and "stops" the database, even though the actual database is still running on port 7474. The screenshots below describe it -

Here, as you see in the "log", the db has actually started up, but neo4j desktop has already thrown a timeout error -

Now, when I start the same DB again, there are conflicts in the ports, because the earlier instance was still running -

and this time, the DB does not start up and throws an exception instead about store.lock and other lock files being in use -

then you will have to manually kill the earlier instance -

This happens every time I start up the database.
