I notice two items on your paste

1. this line - [13/04/2024 03:37:40 AM] Extended Crafting is loaded adding multi block so the "letters" your seeing are the custom builds being loaded more than likely.
2. A lot of optifine errors. Did you add optifine to the pack?

that is log information from infinity for multiblock structures
