so i've been at this for like, three hours now? and its still coming up as 'game crash, and unexpected issue occurred blah blah'. ive done EVERYTHING that i know of and its still not working. i deleted the .minecraft folder, deleted kaspersky, restarted my computer- i had my friend help make sure my files and everything worked too. it works fine- but the second i add in a mod it breaks (i do unpack my mods). any help? im desperate lol
