Just updated to Mac OS Monterey, which resulted in dysfunctioning Rstudio. The program starts, but the main window remains "blank". No response to opening files. Can right-click, with few possible options, but nothing changes.
Cannot enter preferences, but all top-menu options are available, with no real effect.
R as a standalone has normal functionality.
No effect of reinstallation of Rstudio and/or R.
Any suggestions to a solution would be very much appreciated!
