Too late to switch paths?

So I have a bachelors degree in Biology. I'm 22, turning 23 this summer. I don't want to pursue biology anymore. I got into the school at 19 and during my first year a family member passed away and due to that my past issues kind of blew up and I went into therapy. Due to that therapy I have learned to know myself better. I am proud that even though this journey was tough I still graduated.

But to this date: is it too late to start uni again?(free in my country but of course living costs need to be considered as a student. I have 7000€ of debt now. In my country you have to start paying it back two years after graduation meaning If I continue studies its two years after that education. And also now I have strength to work more alongside studies).

I am seriously considering speech pathology but I would be 28 when I graduate. Would that be a red flag to people career wise?
