weird black box sky rendering bug in chunks outside my render distance with voxy which only appears every time i alternate loading my world

I'm currently using MC version 26.1, Voxy version 0.2.15-beta from Modrinth, Java version of 25, Fabric version of 0.19.3
GPU: AMD Radeon (TM) Graphics (integrated/APU)
GPU Driver: AMD Adrenalin 25.8.1, Windows Driver Store version 31.0.21923.11000, OpenGL 3.3.0 Core Profile Context 25.8.1.250617
OS: Windows 11 CoreSingleLanguage 64-bit, 25H2

have a render distance of 12 and sim distance of 8 and are using the following mods

1. Sodium
2. Sodium Extra
3. Lithium
4. Appleskin
5. C2ME
6. Continuity
7. Chunky
8. Mod Menu
9. Zoomify

I am not using any shaders in the following screenshots, and the only resource packs I do have in them are ore highlight shader packs and packs which lower certain effects and items for better visual clarity.

After doing some mingling, I have found the following results:

1. The world I played on in the screenshots (A superflat creative world) worked perfectly fine the first time I loaded it after launching Minecraft, chunks rendered and all using voxy, consistently and normally. However, the moment I leave the world, then join it again, the problem with the black boxes in the sky appears. Rejoining again, makes the world normal; then rejoining again makes the boxes appear. It alternates like this.
2. Waiting for 30 seconds - a minute does not fix the problem
3. Removing all of my mods, except for Voxy, Sodium, and Fabric API still makes the problem appear
4. Removing all of my resource packs makes the problem still persist
5. My Graphics drivers are fully up-to-date
6. Using a different distance rendering mod like Distant Horizons does not make the problem appear
7. Like in the 2nd screenshot, LOD data is not the problem since even after running /voxy import, issue persists

Latest log from when the issue did not appear and voxy worked normally (without any other mods except voxy deps)

Latest log from the 2nd time I played on the world, when the graphics issue did appear (without any other mods except for voxy deps)

Ive tried skimming through other reports similar to this, however i've only found lighting issues within chunks not geometry in the sky like this which makes me think this is a new bug; another detail, this has appeared on 26.2 before, which is why I switched to playing on 26.1 hoping maybe the 26.1 version of voxy was more stable and wouldn't bug out, but obviously the same thing happened.

steps to reproduce (?):

1. launch minecraft, play a world (voxy should work normally)
2. leave the world, then load it again
3. black boxes in the sky within chunks outside of your render distance should appear

let me know if i need to provide more evidence, i might be able to record a screen recording of me reproducing the bug.

Start by reproducing the issue with Voxy, Fabric, Sodium, and the listed Minecraft versions: load a world, leave it, and load it again to observe the alternating black boxes. Compare the attached latest.log files from the working and failing sessions, and check whether /voxy import changes the result. Done means chunks outside render distance render without black boxes after repeated world loads.
