Boot Camp Assistant hangs on partitioning

2017 iMac, 10.15.6 (Catalina), 3Tb Hybrid drive

Attempted to install Windows 10 with Boot Camp Assistant, but hangs on the partitioning step. Anybody have any thoughts on how to get past this? I've tried some of the suggestions I've seen in this forum around killing the process, making sure I'm updated on patches and making sure I have the latest ISO from Microsoft, but to no avail. Here's what I see from diskutil:

iMac, OS X 10.11

Please disconnect/eject Nikon D750.
Run SMC and NVRAM Reset.
Post the output
- sudo fsck_apfs -n -l /dev/rdisk2
- If it is clean, re-run BC Assistant and try to install Windows.
- Do you connect any external storage, but just the Keyboard/Mouse/Trackpad.

The SMC and NVRAM Reset seems to have resolved the issue. I was able to install windows after doing so. Results of the fsck_apfs was no problems found.

Thanks for the help!
