Duwm

Basically I am trying to write a client mod for 1.12.2 and when I try and run it from eclipse it shows the loading screen for Minecraft, and before it is done loading up it crashes. My crash log file says this: crash-2021-07-19_00.04.24-client.txt I have been having this problem for weeks please help! (I have literally reinstalled my entire OS at this point so I've already reinstalled forge and Minecraft)
