No one knows how many bugs claude has because Anthropic auto-closes Issues (or at least used to) if there isn't someone constantly pinging the issue every two weeks. I've contributed to several issues that were confirmed by several other people, which were they were auto-closed after people gave up confirming the problem without any response from Anthropic. They seemingly don't care if it isn't on fire or at least smoldering heavily, which seems really bad in my book if you're trying to make even reasonably good software.
