I thought I posted a solution here two weeks ago, but now it is gone?

Anyway

I have an AMD Radeon RX 6800 XT and GZDoom RT would crash upon start with (Access Violation - tried to read address 0000000000000008).

I didn't have the gzdoom-rt2.ini but I downloaded it from here and put it in the gzdoom-rt-1.0.2
Gist.githubusercontent.com

And then set rt_fluid=false

I found a solution and here is a step by step guide for AMD GPUs:

* Download gzdoom-rt-1.0.2, unzip/exctract it to a folder gzdoom-rt-1.0.2
Put DOOM2.WAD in gzdoom-rt-1.0.2

* Download gzdoom-rt2.ini from here
Gist.github.com
Put it in gzdoom-rt-1.0.2
(or if you already have it, set rt_fluid=false)

* Run gzdoom.exe
* Answer No to proceed without NVIDIA DLSS since you are on AMD
* Enjoy the game
