It is telling you how to solve the problem?

A potential solution has been determined:
- Replace 'Minecraft' (minecraft) 1.18 with 'Minecraft' (minecraft) 1.18.1 (later versions might work too).
- Replace mod 'Fabric Loader' (fabricloader) 0.12.5 (C:\Users\helee\AppData\Roaming.minecraft\libraries\net\fabricmc\fabric-loader\0.12.5\fabric-loader-0.12.5.jar) with mod 'Fabric Loader' (fabricloader) 0.12.12 (later versions might work too).

Alternatively, if you really want to use the older minecraft 1.18 you will need an older version of the fabric api, e.g. see:
