i tried deleting the whole EMC-V2 folder after deleting all the addons and then reinstalling aristois but that didn't work
the crash report --> crash-2021-10-20_09.02.11-client.txt can anyone help?
EDIT: got it to work i went to C:\Users\User\AppData\Roaming.minecraft\libraries\EMC\1.16.5 and deleted optifine and it worked
