Answer to myself, to topic starter and to everybody:

This happens because in "pirate" version of components 6.6.0 from "downloadly ir" file NxColumnsEditor6.dfm is lacking the description of  "object grEditor: TNextGrid6"

If you surely decide to pirate, you may copy-paste this description from older version of this dfm, for example from version 6.3.5, also found on internet wastelands.

I advise not to pirate, but to buy latest components and have normal support from developer :-)

Views Editor opens normally, no error

Version 6.6.0. Delphi 10.4.1

Think the bug is somewhere else. This stack is just an consequence of some inner bug.
