CFA does not work anymore even though I didn't change anything!!

[vanniho1999]

hi guys! Just yesterday I wrote some code to perform a simple CFA. Everything worked perfectly yesterday but today it doesn't work even though I didn't change anything??

I always get this error message:
Error in file(file, "r") : cannot open the connection
In addition: Warning message:
In file(file, "r") : cannot open file '
# CFA
glw_nach =~ nach1 + nach2 + nach3 + nach4 + nach5
glw_marke =~ mar1 + mar2 + mar3 + mar4 + mar5
kb =~ kb1 + kb2 + kb3
': Invalid argument

This is my R code:

ba_data <- read_excel("ba_umfrage_v05_R.xlsx")
ba_data$inf <- recode(ba_data$typ, "1=1; 2=0")

m_model <- '
    
    # CFA
    glw_nach =~ nach1 + nach2 + nach3 + nach4 + nach5 
    glw_marke =~ mar1 + mar2 + mar3 + mar4 + mar5
    kb =~ kb1 + kb2 + kb3
'
m_fit <- cfa(m_model, data=ba_data)

summary(m_fit,
        standardized = TRUE,
        rsquare = TRUE,
        fit.measures = TRUE)

I've also attached some pictures! Hope someone can help me! Thanks!!

I have also made sure that the R file and the xlsx are in the same folder
