[DBeaver 5.0.x] Application "org.jkiss.dbeaver.core.application.standalone" could not be found in the registry.

From time to time DBeaver CE refuses to start with mentioned exception. Apparently it is able to write bork in its own configuration such that it cannot process it properly itself. To fix this, remove config directory:

${HOME}/.dbeaver4/configuration

Earlier versions (3.x at least) have been affected too.

[LibreOffice Calc] ERR:502 in vlookup (sverweis)

Make sure that the referenced column is not outside the defined area. hlookup/wverweis probably analogous.
