thank you so much. I haven't had time to install R 4.0, I still have R 4.1 where I had the original problem.
I ran
update.packages(ask = FALSE, checkBuilt = TRUE)
and the message was
There are binary versions available but the source versions are later:
binary source needs_compilation
reprex 2.0.0 2.0.1 FALSE
rsconnect 0.8.18 0.8.24 FALSE
tinytex 0.32 0.33 FALSE
vroom 1.5.3 1.5.4 TRUE
after the update, it works ! Thank you
