In order to keep using certain mods, some friends and I created a server through Aternos using version 1.20 of Minecraft.
I installed this mod for version 1.19.2 (cfm-7.0.0-pre35-1.19.2), and read whatever file was readable in the .jar. According to the file [mods.toml], this version should be compatible with Minecraft 1.20, but when starting up the game an error comes up (screenshots below). I'm very new to modded Minecraft so I have no idea on how to solve this.

• Minecraft Version: 1.20
• Mod Version: cfm-7.0.0-pre35-1.19.2

[1.19.2, 1.20) translates into minecraft versions greater or equal to 1.19.2 but less than 1.20. The message on the error log says this.
