Neo4j 4.0.x not working after upgrade on Neo4j Desktop 1.2.4

[vvvasilev]

Hi everyone,
I just can't get neo4j 4 to work and have my content from 3.5.15 migrated. So what I tried:

• clean install of Desktop 1.2.4 on Windows 10
  Test 1:
• created new database 4.0.x and started it. The database is accessible, nodes can be created manually (browser) and through my webapp
• Loaded a dump from my 3.5.15 installation.
• When starting, the database displays the Password message from the screenshot

Test 2:

• created a 3.5.15 graph, loaded the dump from my prod server. Started without problems.
• Stopped the database and upgraded it to 4.0.1
• During starting displays the Password error from the screenshot.

Please note that entering no known password - my and defaults, is accepted.
