Hypothetically, what would you do if Bitcoin's code broke?

All of a sudden addresses are able to double spend, people are seeing transactions that they haven't done, etc. Obviously this would plummet the price as faith would be lost in what was supposed to be hard code. The integrity in blockchain technology would start getting questioned and I'd assume most trust would never come back much like algorithmic stablecoins.

I would remove everything and wait to see what happens, that's if I can even move any of my coins or I had any left. Crypto's backbone is it's security and if the oldest and most reputable crypto we have is having security exploits I can't keep my money in it. It's one thing for an altcoin has issues, but at this point Bitcoin is like the energy generator to the whole building. If it goes down, I don't feel as comfortable about crypto. What would you do?
