library(tidyverse)
library(MatchIt)

dat <- tibble(y = rbinom(2000, 1, 0.3), 
x1 = rnorm(2000, 1.5, 0.87),
x2 = as.factor(rbinom(2000, 2, 0.73)),
x3 =  as.factor(as.vector(rmultinom(2000, 2, c(0.3, 0.5, 0.2)))
)

matchMod <- matchit(y ~ x1 +  x2 + x3 ,
                    data = dat,
                    method = "nearest",
                    distance = "glm",
                    caliper = 0.1,
                    ratio = 1,

While I try to run the above code RStudio version 2025.09.0 crashes but in my earlier version RStudio version 2025.05.1 does run the code properly.

Can you guys help where does it go wrong?
