I am using Windows 10. I recently tried to update R from 4.3.0 to the current version 4.4.1. Since then, I can’t open one of my projects anymore. This project uses version control (GitLab) which I connected via SSH key. All other projects, normal R scripts in Rstudio and opening R itself work fine.

The failure report states: “An existing connection was terminated by the host computer
by the host computer”.

Is there a way to reconnect to the project?.

I tried reinstalling the old R Version, reinstalling Rstudio and to remove all startup files such as .Rprofile, .Renviron, and .RData from your initial working directory but they problem remains. I dont have any firewall, proxy settings and antimalware which should hinder Rstudio.
