Which sectors in the tech industry have the most issues with their bugs?

Bit of an odd question, but I'd really love to hear from people that have worked in multiple sectors and have some insights on which companies struggled the most with their bug problems.

I suspect things like FinTech/Finance/Healthcare, where the quality of data is paramount to the point that'; if numbers or records are incorrect, can cause their users to lose a lot of money.

But I've also personally worked in e-commerce and know if there is a UX blocking bug on the checkout, you're constantly losing money and customers until it's resolved.

Curious for some open insights and dialogue on which sectors seem to be the most encumbered.
