i just finished installing forge and downloading mods. all of them are for 1.14, all of them are through forge, and all of them should be compatible. i have forge 1.14.3 for the latest release. im using java edition. i use a windows 10 laptop. when i searched this specific stack trace for possible fixes, all that came up were problems for earlier versions or issues not related to minecraft. i checked my logs folder and a debug log didnt appear. i did have my game output on while the crash happened, though.
my launcher_log is on github here.
what i understand from the research i did on reading crash logs is that the problem is caused by a duplicate key.
the problem is, i have no idea what would be causing it.
any help figuring out whats going on here would be appreciated a lot! this is day two of me troubleshooting mods, lol
