Errors on mod loading and then crash on startup

so ive been working on a modpack for me and one other friend to play, I compiled and tested the mod list on the curse forge loader but I haven't been able to get past loading with aternos. there are multiple errors about unsigned core mods but all of the ones listed in the errors are necessary for gameplay. if they are the problem I understand that some compromise will have to be made but I would prefer to make sure that there is no other way around it. any help would be appreciated.

the crash log is located here: https://mclo.gs/J8SjCLG

thank you for the advice but it hasn't seemed to change anything, it crashed around the same time and still has all of the same errors. thanks for the help.
