Unable to install pyocd in latest version of Anaconda

I'm trying to set up our usual Anaconda development environment on a new Windows 10 PC. I downloaded the latest version of Anaconda last week (version 2023.09, I believe), and I'm having trouble installing pyocd. pyocd installed easily on all the other PCs several months ago.


I ran conda using Anaconda Powershell Prompt in administrator mode. Here's what conda returns:
(base) PS C:\WINDOWS\system32> conda install -c conda-forge pyocd
>> Collecting package metadata (current_repodata.json): done
Solving environment: unsuccessful initial attempt using frozen solve. Retrying with flexible solve.

The error messages are pretty unhelpful - I'd try installing downrev packages, but I don't know which ones to downgrade. Any ideas what's going on?


UPDATE
I updated conda, and now it actually gives me actionable error messages:
(base) PS C:\WINDOWS\system32> conda install -c conda-forge pyocd
