Collectible Card Game Headquarters

Describe the Bug:

Attempting to cast Prince of Thralls crashes the game. Dump.txt is not updated.

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)

Holidays 2021 ad1a6f8 - gauntlet

What exactly should be the correct behavior/interaction?

Casts

I have no idea what causes the crash but it can be cast without crashing in a clean game, at least it does so in dev.
However, if an opponent creature dies, it's ability triggers as it should but if opponent doesn't pay 3 life, the creature isn't put onto the battlefield under Prince of Thralls's controller.
