Hello! I am new to modding.

The mods I'm trying to use are Fabric, Optifabric, Optifine, Xaero's Minimap, and Xaero's Worldmap, all of which I have downloaded the newest versions compatible with 1.18. I get this same crash report when trying to open single-player worlds, multiplayer worlds, and Minecraft realms.

OptiFabric error:

try uninstall optifine and optifabric, and install sodium and iris

According to these, optifabric hasn't been updated to work with optifine pre8

Chocohead/OptiFabric#492
Chocohead/OptiFabric#491

You should report optifine issues on that project.

Switching from Optifine pre8 to Optifine pre7 ended up working, thank you so much!
