As I said in my second comment, I’ve tested disabling all plugins. This removes the noindex. when I activate only Yoast, the noindex appears again.
With only yoast active, I see this
<!DOCTYPE html><html lang="en-US"><head> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name='robots' content='noindex, follow' />

With all plugins disabled, including mu-plugins, I see this
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name='robots' content='max-image-preview:large' />

I also tested switching from twentytwentyfour to twentytwentythree, and see the same.
Thanks for you help!
