Hi, I freshly installed Elasticsearch (trial license), then ran the elasticsearch-setup-passwords.bat and setup the passwords. Then I copied the Kibana zip contents and ran kibana.bat. I got all sorts of [logical] access errors so added to kibana.yml the following entries 
elasticsearch.username: "kibana_system"
elasticsearch.password: "<>"
#xpack.monitoring.elasticsearch.username: "kibana_system"
#xpack.monitoring.elasticsearch.password: "<>"
xpack.security.encryptionKey: "<>"
xpack.reporting.encryptionKey: "<>"
xpack.encryptedSavedObjects.encryptionKey: "<>"
(I obviously used other passwords and [longer] encryption keys).
Elastic and Kibana run well, elastic is status green, Kibana " http server running at http://localhost:5601"
When I then go to http://localhost:5601/spaces/space_selector#/tutorial_directory/sampleData which is I guess the standard place to start, I get a login screen, login as user "kibana_system", and then I get stuck on a page (see screenshot) where he tries to get me a list of spaces. Even if I let it run for an hour, he does not get out of this.
Yesterday I installed a fresh elastic/kibala install with the basic settings, no authentication, no extra Xpack things. That worked well, but I wanted to use the new data ingest manager, that requires superuser access, so I got into the fresh installing trial license with user access.....
I cannot find other posts on this problem, hope you guys can help!
best regards,
Simon
