My mod has compilation errors for every mod element when I try to run client

I opened a workspace that I hadn't worked on in a while in 2021.2 and it caused a bunch of compilation errors when I tried to run client. I tried to put this as a issue on the GitHub issue tracker but it didn't work for some reason so I am putting it here. The last time I had opened the mod was in Mcreator 2021.1. Here is the workspace folder for the mod in a zip file: https://drive.google.com/file/d/1CMN-A5iCe1gZYtcP_SA-j5tEz4jkGI2s/view?…

Here is what the console said when I tried to run client:  https://pastebin.com/Bera6WU5
