Today when booting up my MC crashed with the following crashreport

Disabling /DankNull in Twitch launcher solved it, so looks like issue is at least related to DankNull

Getting the same crash. Previous versions of the mod have been archived too which means users can't easily downgrade to fix it.

Edit: Downgrade p455w0rd's Library to .151.

p455w0rd has currently scrapped /dank/null due to hate they've been receiving from people that have never developed a thing in their lives...

Same thing happened here. I used an earlier version and that fixed it for me. I think the problem is with an update in DankNull.
DankNull-1.12-1.4.46.zip

I, just, can't, think, of the words to express my sorrow for the Mod Author, I know how bad it can get even though I'm not a modder... Imagine the hate people have for mods that some people might think iss cheaty like X-Ray mods. This mod lets you store tons (literally) of blocks in 1 source. I hope the OP or anyone who picks up the mantle of this mod will regain composure and have a better life from this...

BTW, it says in that link, the solution is to downgrade the Password Library file... or just uninstall Dank.

Can confirm that the pack loads correctly with the latest /dank/null and Lib. Cheers p455w0rd
