How to attach file to an email in Sonoma?

Normally (before I installed Sonoma) I create an email (in apple mail) and then select the paperclip (attach) and then browse to the file I want to attach.

That isn't working in Sonoma!

I finally figured out that I have to click the arrow next to the folder in the browse window, but even then when I find the file, it doesn't attach.

I'm forced to go to the finder window and drag the file into the email.

I've looked in Mail settings but no help there.

The image shows me getting to the correct folder but not being able to select the file.
