Mods do not work across Minecraft versions. You cannot use a release designed for an earlier version on 1.16.1.
Also don't change the extension of log files (or any files, unless you know what you are doing).
Closed since this is not an issue on the mod.

Hello
I hadn't seen the version so when you can get 1.16.1
