L8.9B2: repeatable CRASH double-clicking in some bibles

Trying to recreate a situation from this German language thread, I found a repeatable crash in Logos 8.9 Beta 2: 

• open German bible "Zurcher" or "Luther 1984" to e.g. Rom 16 [or Mt 15]
• double click a word in the bible text, such as Phoebe or Junia(s) or empfehle [or Sohn or Wort]
• okay behavior:
• in case of an RI bible, the highest prioritized lexicon opens for the underlying Greek lemma (this works for e.g. English bibles NIV 1984, NIV 2011, CSB, ESV and German bibles Luther 2017 and Schlachter 2000)
• otherwise a dictionary opens (this works for e.g. The Message, Douay-Rheims, Geneva Bible and German Protestantenbibel as well as for non-bible-text in Zurcher)
• if no dictionary entry exists, an Everything search opens (some words in Geneva or Protestantenbibel or a Schlachter PBB bible, as well as non-bible-text in Zurcher)
• actual behavior with Zurcher bible (non-RI) and with Luther 1984 (RI, this is probably the most-used German bible in Logos): Logos crashes with
  
  Error ID: 1085 - Error detail: NullReferenceException: Object reference not set to an instance of an object.

When Power Lookup tab is open, it remains empty through all of my tests. So far I haven't been able to repeat the crash with an English language bible.

EDIT: checked all 26 German-Language bibles I own in Logos edition (which should be all existing ones, from SESB times onward). All are working okay except the two mentioned above plus the four non-RI bibles Einheitsübersetzung 1980, Revised Elberfelder 1985, Menge and Die Gute Nachricht
