Fix

I noticed that if I take the following action, I can access the virtual system, though I'm unsure of the impact it has on Nextcloud Desktop's ability to track what has synced vs not synced.

cd /Users/tyler/Library/CloudStorage
sudo mv Nextcloud-tyler@my.domain.app Nextcloud-tyler
killall Finder
killall fileproviderd

open /Users/tyler/Library/CloudStorage/Nextcloud-tyler/
