I am also experiencing a similar problem: when I try to resume from sleep it would let me put the password but then it won't go anywhere from there.
I have noticed however that this behavior varies with how long it's been asleep and with or without the external monitor connected... Back with Zorin 16 Core it didn't happen, though it would just shut itself off after a few hours and would have to restart anyways 
When I contacted support they said to: 1. set the power mode to balanced or saving, 2. use Xorg instead of Wayland and 3. update the bios. I have recently updated the BIOS and perhaps that helped... together with the solution offered in this thread.
I'll report if it worked later.
