Building and packaging RStudio for conda is notoriously difficult (for example see here and here for an idea of how long it took to get an initial version working). More recent versions aren't available from conda-forge because no one has yet fixed the new build errors. See the open Pull Requests for the current update attempts Pull requests · conda-forge/rstudio-feedstock · GitHub
One suggestion: try downgrading R to be the same version that was current when that version of RStudio was released in December 2022 (I think this would be R 4.2.2)
