Using Hyper-V, I can't get past the unlock drive

When I type my password, it only shows what is being typed in the top left and doesn't actually input the password

You need to disable the "splash" screen. Once you power on, when it asks to choose the operating system (Ubuntu, Advanced, etc.) , press E . It will take you to another screen, remove the string "splash" from the line which says something like "quiet splash video="...

Press Ctrl+X to boot without splash.

After the system boots up, to save this change, you need to modify the file /etc/default/grub and remove "splash" from the line beginning with "GRUB_CMDLINE_LINUX_DEFAULT=".

Don't forget to do a

sudo update-grub

In the end I reinstalled Ubuntu with Secure Boot disabled and not encrypting the drive

I had the same problem. It appears to occur if you set the VM's ram to 1024 (the default) and OS runs out of memory.

To fix: turn off the VM, go to settings and change the RAM under Memory to 2048.
