The same thing happened to me. It would give me a few seconds to type then freeze. I saw people saying type in “deafault_password” to get through this, but the system was freezing after a few seconds.
The next solution I saw was to Format Data using TWRP. That got me past the password screen, but the device would freeze on the home screen shown in my original post. Also, at this point when I would return to recovery I would see a “Mount Decrypt Data” “Enter Password” screen. I would hit cancel and try formatting a few more times.
The next thing I tried was flashing the rom rebooting into recovery and then flashing gapps before the first boot. This seemed to stop the freezing, but then I got an a continuous error that pixel set up had crashed. At this point I gave up and installed Lineage 15.1 instead.
