What to make of a girl rejecting you because you have one friend that’s a female?

Met this girl on a dating app last week; we’ve been texting back n forth and even talked on the phone 3 times. We were planning on meeting this week.
Thought we had a great connection until I mentioned that I was going to go workout with my friend (who’s a girl). She immediately stated that she was suspicious of that and stopped texting me. I tried clearing it up that she’s just a friend, stated I wouldn’t be using the dating app otherwise if so.

This resulted in her telling me to leave her alone and her blocking me on social media.
Any ideas?
