• Always check you are using the latest version of the mods and its dependencies
• Remove mod that enhances Minecraft: Optifine, Sodium, others. The issue still persists.
• If you are unsure which mod is the culprit.
  Disable all of your mods and enable them 1-2 mods each time to isolate the culprit

Crashes on startup with an error: §7java.lang.UnsupportedOperationException: Base block cant be null
I apologize if the issue is with the other mod. Since I do not know which mod is the problem, I am making an issue on both mods.

what's the full name of JAOPCA?

Just A Ore Processing Compatibility Attempt
I apologize for using the acronym, it's found in Curseforge as JAOPCA and the full name is only used in the description.

No worries. I am somewhat familiar with that JAOPCA, but can't remember the full name. IIRC, it doesn't have any wood variants, right? I'll take a look at the curseforge's page

try to disable Quark and see if the crash is solved. FYI, JAOPCA is not supported by EveryCompat. but Quark is.

EDIT:
did you modify the configuration of Quark so some blocks are not available via Minecraft?

Disabling Quark allows the game to load. Quark and Every Compat work fine, Every Compat and JAOPCA work fine, the combination of all three crashes. I'm sorry I didn't notice this before.

The only edits I made to Quark's config were to disable Limestone (overlaps with Create) and Monster Boxes (sort of overlaps with Apotheosis). However, re-enabling them did not stop the game from crashing.

I can replicate a combination of 3 mods causing the crash. I've seen a combination of 4 mods that caused the crash. To the present day, it's not solved. I have no clue what caused the crash. Unfortunately, I have no idea what caused the crash above.
that is very rare.

a bit more information. from what I learned so far, JAOPCA supports Quark and has dynamic data generation. Where it adds the dust from other mods to the system. u get the idea.

My best guess is the order of mods being loaded is like this:

1. JAOPCA loaded
2. EveryComp loaded.
3. Quark loaded

note that EveryComp should be last after Quark or other mods so it can get other blocks from these mods. that may be the cause of the crash.

This issue didn't happen with older versions of everycomp tho so some change in 2.6.42 broke things

I see. that's a useful info.

It has been fixed with everycomp-1.20-2.6.45
