Revamp and DLC

I'm tired. I did a completely regular playthrough on a new character.

Future Saga and U6 DLCs worked, but that could be a blunder.

Mods are definitely not the cause as disabling revamp allows it to work normally. Talking to the PQ bot causes the game to crash.

The save file must be completely screwed because nothing I do fixes anything and there's no crash log telling me what happened.

What do people do at this point? What can I do? At the very least I have 5 other vanilla CaCs so not all is lost. But how could I possibly fix Revamp causing DLC infinite loading and PQ crashes?
