Today I updated r to the latest version and it turns out that I am unable to install the 'goseq' package, which is necessary to perform my analysis. I get the message: package 'goseq' is not available for Bioconductor version '3.19'. I cannot change the bioconductor version to an older one, because the older ones are not compatible with the latest version of R (4.4). in turn, when I try to run older versions of R, a window keeps popping up that the session has been disconnected and to try to reconnect

It is true that goseq isn't available for Bioc 3.19 (as at 4 May 2024).

In the meantime, you could consider using the goana() and kegga() functions in the limma package, which can also do gene-length-adjusted GO analysis as provided by goseq.
