Cannot draw a wire after upgrading Promis.E CONNECT from U3 to U4

After upgrading promis.e CONNECT from Update 3 to Update 4, I am not able to draw wires - see video:

The situation happens with delivered examples with default workspaces/worksets and with projects restored from V8i backups.

I am in schematic mode, so issue described there: seems not to be related with the issue.
