Am I hacked? EXC_CRASH (SIGABRT)

I was in my bank and was watching a livestream on YouTube. Suddenly Safari crashed and I got a fairly long error message window which got sent to Apple.

This has never happened before, and I started the process of reinstalling the system. If this is the case, should I worry about my iPhone or iCloud account as well?

The message: “object cannot be nil.”

Is this something that can happen by random?

This is part of the message:
