I started a director job at a new company.

I started a director job at a new company. I met my boss for about 30 min during my 1st week. She was going to set up weekly mtgs but hasn't. I talked to her once for 5 min 2 weeks ago. She said I'm doing great. Company has no formal performance tracking or even goals. I put in for time off (2days) that I'll lose at year end. I'm not asking for the holidays off. She hasn't approved them & when I emailed her, I got no response. I set up a call for tomorrow. I'm in my 1st 90 days. I feel like she's ghosting me. I haven't said anything to my team yet they make comments like, please stay or don't leave. I found out it's because a few others quit last year at this time because of my boss. Should I be looking for a new job or worried about this one?
