I have 11 mods running mostly for more relics, cards, and events. One in particular is the mod that gives quests and the reward for killing a nightmare makes the run Endless. After starting the 2nd run, I crashed three times at an Alpha Nightmare event in Act 2, then it crashed again at the boss of Act 2, which was The Stone Colossus. Now it immediately crashes when I click the continue run button. This is the error I got after debugging.
