Im not seeing a mod menu button in the esc menu, whether its in single player or multiplayer.
Im on modmenu-13.0.3.
Id also like to note that im on the latest version of lunar client, how ever when tested on vanilla mc im still having the same issue.

hi, i think i found a solution by deleting the connetcor extras mod in the mods folder.i play on version 1.20.1forge,
