Running the exact same code in R 4.1 + the newest Rstudio version

creates this for me without any problem

It seems that you have somehow a wrong patchwork package installed.

The current version is patchwork_1.1.1 and patchwork_2.4 does not exist yet. I suggest that you install patchwork again from cran. Eg:

install.packages("patchwork",repos = "https://cloud.r-project.org")

I had the same issue, caused by there being two packages both called patchwork...

Installing via install.packages("patchwork", repos = "https://cloud.r-project.org") solved the problem for me.

I had a look through the results of options('repos') and it looks like the patchwork listed at https://r-forge.r-project.org/projects/patchwork/ is incorrect (this version of patchwork offers "Allele-specific Copy-number analysis for whole-genome sequenced data in CompleteGenomics or BAM format").
