After the Windows11 update my RStudio opened only being blank. I could not access any settings or scripts I used to have open. So I deinstalled it + my R-version and installed the latest R and RStudio versions, then it told me “R does not appear to be installed”, although it is.

I since even tried to downgrade to older versions up until 2022 with the according R-versions. When launching, RStudio even found the old R version. I manually selcted it, even tried with changing the rendering setting to “Software”, but even that did not help. Just a blank, minimized window appears, that I cannot fully open.

Don’t know what to try anymore, any ideas would be very much appreciated.
