All modpacks crash upon opening MAC

[CallMeKimberly]

Right lads, I'm trying to play some modpacks on my Macbook, they download just fine. But when I try to open a modpack it crashes immediately & says ''MODPACK QUIT UNEXPECTEDLY'' 

My MacOS version is Big Sur, I have Java 8 update 271, I have no idea what kinda specs you folks need to help me this is the first time I'm posting something here.

Not a discussion about AoTB, not a AoTB bug. Moved to Platform Pagoda.

I also have MacOS Big Sur and I'm having the same issue. Any modpack I try to open crashes. Here's an error message I got from one of the modpack. https://pastebin.com/wKArq85w

Remove java 8u271. Install java 8u251. https://javadl.oracle.com/webapps/download/GetFile/1.8.0_251-b08/3d5a2bb8f8d4428bbe94aed7ec7ae784/unix-i586/jdk-8u251-macosx-x64.dmg
