Error: object 'dodge' not found - Plot not working anymore

Question

This graph was working perfectly before, and now it is giving me the error "Error: object 'dodge' not found". It used to work perfectly fine, and I didn't change the code. Does someone have any idea of what could be going on?

Thank you.

Here is the code and what the graph used to look like.

library(lfe)
library(dplyr)
library(tidyverse)
library(broom)
library(data.table) 
library(lfe) 
library(texreg) # not working
library(hdm) 
library(parallel)
library(coefplot)
library(ggplot2)
library(GGally)
library(broom.helpers)

I tried tracing back the error, and this is what I get.
