we had a main modpack that we updated and changed mods on which resulted in this issue. thinking it was corrupted, we remade the pack entirely and gave it a fresh install of each mod through the curseforge app. meaning unedited, new mods. but no matter what we did we still received this issue. we researched as much as we could to troubleshoot on our own. we can run other packs just fine.
we have deleted from individual to the entire config folder.
we have tried changing forge versions or downgrading recently updated mods.
the first crash log gave a few mods in name like modern fix, puzzles lib and something else. not necessarily saying they were issues, we still removed them and their dependents.

this was the before https://mclo.gs/vCK8pDC

this was after the mod removals https://mclo.gs/uPOCoBS

any help is greatly appreciated 

 

Also add the latest.log (logs-folder)

latest https://mclo.gs/HdLSJTR

debug https://mclo.gs/mYkppP4

Add the mod theoneprobe or remove arsmagicalegacy

theoneprobe, the alternative to waila?

Yes - looks like arsmagicalegacy requires this mod

Or it is an issue with ascended_quark

ive added theoneprobe, crashed. i removed ascended quark and it works. make it make sense.
