If you matched the technical requirements, then it seems exceptionally open way of saying "you are not good culture fit".

Maybe next step is to figure out WHY you are perceived as bad culture fit?

Do you have any obvious issues like being very nervous in interviews, or underlying general issues such as anxiety, or just being a very quiet person?

> nervous in interviews, or underlying general issues such as anxiety, or just being a very quiet person?

Yes, all three. The nervousness and anxiety are especially heightened during interviews, but I don't experience either on the job. Does that make me not a culture fit?

Well, if you have solid technical experience, but are being very nervous and quiet, and a recruiter tells you straight to face that "culture fit is more important", then the reason for failing 30/30 interviews seems fairly clear.

Why don't you A/B test yourself? Take double dose of your favorite anxiolytic and dress more casually to next interview and see what happens. If you fail again then it's 31/31 and not a big loss.
