RadiantGI crashes display driver or game on AMD 7900 XTX graphics card #14

Description

@Markxy

When enabling the shader with ReShade, either the display driver (causing the game window not to draw anymore) or the game crashes (hangs indefinitely).

Game is CSGO which uses DX9.
OS is Windows 10
Display drivers: tried multiple, 23.1.1, 23.2.1, 23.2.2
Had this issue on multiple computers as well, both had the same AMD card.
Tested with ReShade 5.0.2 and 5.6
The RadiantGI.fx file is the same as the in this repo.
Tried clearing the shader cache.

Haven't had this issue using Nvidia graphics cards (3000 series). Also no other ReShade shader I tested causes this behaviour with this AMD card.

Unfortunately I don't have any crashdumps as it doesn't seem to produce one, nor do ReShade logs tell anything.
There is one preprocessor warning:

^^ the last glyphs spell out "T A M P E R E D" when viewing with notepad++, not sure what that's about.
When I diff the RadiantGI.fx here vs on my disk, they are identical.

Here is what my RadiantGI-related conf looks like in the ReShade preset .ini file:
