Same card here (RX 7900 XTX, Ryzen 9 3950X, Windows 11), same blocky/pixelated textures. One finding that might help:

The blocky textures come from the ASTC → BC3 re-encoding of large textures. Launching with RX_VK_ASTC_RGBA8=1 (it turns off bc_ready() in gpu/vk/vk_texture.cpp, so those textures stay RGBA8) makes the squares go away at the same spot in Kokiri Forest. You can set it from PowerShell before starting the game:

$env:RX_VK_ASTC_RGBA8 = '1'; .\hookshot.exe

Cost on a 24 GB card: textures go up to ~9 GB (log: textures 9250 MB, budget 16624 MB) and it still holds 60 fps, so it is a usable workaround on cards with a lot of VRAM. On 8-12 GB cards it may page.

So on AMD the BC3 encoder path (ASTC decode into the scratch → bc_encoder.comp → vkCmdCopyBufferToImage) produces wrong blocks. I'm looking at why and will follow up with a fix if I find it.

What it does not fix (still present with RGBA8): water drawn as flat opaque green, black leaves/vines (alpha-tested foliage), and the hard-edged light shafts at the Deku Tree. Those look like separate issues (#61, #64, #84).

Separately, PR #102 fixes the black 3D when Resolution 100% is saved in the options at startup.

Tracked in #1006, follow there. That issue collects every report of AMD-specific rendering problems, and this one is linked from it with its GPU, version and log details. If it still happens on v2.0.6 (https://github.com/NotRexed/Hookshot/releases/tag/v2.0.6; Update next to Play in the launcher), please add a comment there with your hookshot_log.txt.
