DBUI oracle connection freezes when connecting

[ciapecki]

I am on macos. Neovim 0.10.3
Plugins installed:
Plug 'tpope/vim-dadbod' Plug 'kristijanhusak/vim-dadbod-ui' Plug 'kristijanhusak/vim-dadbod-completion' " Optional: For completion support

➜ Downloads cat ~/.config/db_ui/connections.json [{"url":"oracle://cx_dqm_grp@mktcxdap_low","name":"cx_dqm_grp@mktcxdap_low"}]

When I execute :DBUI and provide password, connection seems to be established, but the nvim freezes, I cannot move with CTRL+W+L to right pane.

~ [DBUI] ~ Connected to db cx_dqm_grp@mktcxdap_low ~ after 7.881810 sec.

From here I can just CTRL+C then move to right pane, but then when I execute :DB then I get DB: no URL

What works though is in the left pane with connections when I click on New query I am put in new buffer in right pane and I can successfully execute commands.
But I need to edit existing files. How can I configure that properly?

thanks,
Chris

UPDATE:
The connection is finally established, it takes just long time (ca.2 minutes - because of the size of the database I connect to with many schemas and a lot of tables).
Is there a way not to load in front all of the objects from all available schemas, just the schema I log as?
