So I've gotten ATM7, and then I deleted a few mods because I'm too lazy to get the other forge version. This is not important though. The actual issue is a texture issue, the error code was "The game crashed whilst rendering overlay
Error: com.electronwill.nightconfig.core.io.WritingException: An I/O error occured
Exit Code: -1". Now, I've seen other people have this issue, but their posts got closed. The crash report: https://pastebin.com/tgy4T8ee
Please fix.

The process cannot access the file because it is being used by another process
Windows ftw. Reboot and relaunch the pack.
Or use task manager to find the duplicate task and end it.
