What happened?

1st floor, RPD, Long Corridor (20C)
Entering into this room crashes the game
Item inventory includes Grenade Launcher in Lighter Slot (w/Flame Rounds)
Current, main inventory has Magnum, Diamond Key, Ink Ribbons
Using the Debug menu to enter into 20C Long Corridor also crashes the game, regardless of entering via any entrance.

Trying to solve for final Knight's Plug, both Red Jewels. I can already access 3rd floor King's Plug, because I have Golden Cogwheel and Crank.

Looking at seed log, I only see ammo and enemy changes within 20C, 20D (Cog Room), 20E (Mirror Room).
