@vxshelf hi there it seems that optifabric failed to download properly please follow these steps to fix the issue,
go to \.minecraft\ mods and delete optifine (if there isn't any you can skip this step)
go to \.minecraft\libraries\me\deftware\EMC-F-v2\latest-1.XX.X and delete optifabric (you can change the 1.XX.X into the version your using)
2,5. [OPTIONAL] navigate to \.minecraft\libraries\EMC\1.XX.X and delete optifine.jar
load up the game and go to a singleplayer world, wait for a message saying installing optifine please wait and restart the game once the notification finished installing (if you follow step 2,5 then install it again at the addon marketplace on the pause menu, wait for it to instruct you to restart then close the game properly DO NOT X THE GAME use the menu to exit the game avoiding any issues)
@cuong The file isn't a zip it is a jar installer, you need to have java installed to run it, you can get java here https://www.java.com/en/download/ and then right click > open with > and select java, you may need to restart your pc after downloading and installing it.
@earl Working fine for me. does it happen regardless of what the text is? Do you have any fabric mods? Do you have OptiFine?
Edit: When I read your original post, I thought you meant that it was occuring in Singleplayer. If it occurs in Multiplayer, this is something the server has modified. Whether it be a censor plugin or something else.
@farahalraee You need to follow the steps given, not reinstall. If you are on MultiMC the "me" folder is in MultiMC/libraries, not the instance. All games & launcher must be close while deleting the folder.
You can hold shift on that screen and it will show you the directory of the file that you need to delete.
