iTunes freezes when iPhone plugged in

I just got a new PC, and I haven't been able to get iTunes to sync with my iPhone. When I have iTunes open and plug in my phone, iTunes freezes. Sometimes if I wait long enough (several minutes), iTunes eventually shows my phone, but it still freezes/runs very slowly. If I'm able to click on my phone, it shows all content on the phone as "Other" and backup attempts fail.

Accessing my iPhone via Windows Explorer works fine, and I was able to download a few hundred photos without issues.

iTunes works fine with my iPod Classic 160. No freezes, and a sync worked fine.

I've tried several different USB ports on my PC (2.0, 3.1 gen 1, 3.1 gen 2), as well as different cables. I've also uninstalled and reinstalled iTunes a few times. The last time I ran the installer as an Administrator. I've also tried manually updating the Apple Mobile Device USB Driver as shown here:

I'm seeing the following errors in the iTunes logs when I plug my phone in (this is 3 separate attempts):
