Client Crashing When Trying to Open Mod

Upvotes: 1
Issue description

Every time I try to open the client with my mod workspace loaded, it would crash right before finishing opening the game. I tried opening it in the Minecraft launcher and the same results presented themselves. I have the crash log here that I got from the launcher to at least try and help a bit. I have also included a copy of the .jar file.
