Crash whenever loading into world after earlier crash

[gradientogames]

so I made two quests in the mod: first a quest to get any log and second to get a full set of wooden tools, but after I save the second quest and I exit the book, the game just crashes without a crash report, so I try reloading into the the world and it crashes everytime with the same crash report: crash-2021-07-19_15.07.04-client.txt

I have a whole bunch of mods but the ones related to better questing are: BetterQuesting 3.5.329, Better Questing multiblock structure intergration 1.0.6, Questbook 3.1.1, Rf expansion 3.4.31, Standard expansion 3.4.173, minecraft forge 1.12.2 14.23.5.2854.

I have a feeling that the better questing mod is 3.5 and standard expansion is 3.4 but the standard expansion can only go to 3.4.
