game not starting

[wind magnet]

my log:https://mclo.gs/6gyLI9i i added a few mods and in the process of trying to make all the mods work with each other i needed to update to a slightly newer version of fabric and after that it gave me this message in the logs " [19:46:25] [main/WARN]: Warnings were found!

• 'Minecraft' (minecraft) 1.20.1 recommends any version after 5.4.1 of Fabulously Optimized, which is missing!
  • You should install any version after 5.4.1 of Fabulously Optimized for the optimal experience."
