Dock not showing up after update to Catalina

I have this same issue. The dock is just gone. When I bring up the dock settings and move the "size" slider around, the dock becomes visible for as long as I click. Once I let go, the dock disappears. I tried clicking on the invisible icons after the dock disappears, nothing. If I try to minimize a window, it will freeze the application/window. If I toggle the size slider again, the dock will become visible and the windows will minimize into the dock. Once I let go, the dock disappears again into the void. I can bring a window up again by CMD + TAB, then sliding the size slider, and then the window will come up out of the dock. My OS is basically unusable at the moment.

My Specs:

OS Catalina 10.15

MacBook Pro (13-inch, 2017, Two Thunderbolt 3 ports)

Processor: 2.3 GHz Dual-Core Intel Core i5

Memory: 8 GB 2133 MHz LPDDR3

Graphics: Radeon RX Vega 56 8 GB

You can also open terminal and write there: killall Dock

This has solved the issue for me, though with an external display, this happens always.. So opening terminal is the fastest for me to get it back..

TRY----- FINDER>SERVICES>SERVICES PREF>click LAUNCHPAD & DOCK>UNTICK DOCK HIDING ON/OFF

I have the same problem, tried this but nothing happens. The dock is permanently missing. On restart it return, next restart it's missing, etc. Just as described above

Solved bug by in my case by unplugging one of my two monitors when rebooting. Dock appears as normal then I plug-in second monitor and continue as normal.
