This appears to be a concurrency bug in EvilCraft when it initializes keybindings. These types of issues will only happen sometimes during the launch.

Unfortunately, ModernFix 1.16 is no longer receiving updates, but I would accept a PR from someone adding a patch for EvilCraft that fixes this issue.
