I am having this exact issue since the last update. Here is the result of an ipconfig /all. My PiHole is at 192.168.0.133. PiHole just shows localhost and adds are getting through.
I removed pi-hole and rebooted. I could see the network but not the internet. I removed both entries in the dhcpcd.conf for the network adapters. I rebooted and could see the internet again. Installed pi-hole and rebooted.
