Last error was: QLocalSocket: Remote closed The R backend will be shut down immediately. This means, you can not use any more functions that rely on it. I.e. you can do hardly anything at all, not even save the workspace (but if you're lucky, R already did that). What you can do, however, is save any open command-files, the output, or copy data out of open data editors. Quit RKWard after that. Sorry!

Thanks for reporting. This is a known bug when using RKWard 0.7.2 with R 4.1.x, but has been fixed in RKWard 0.7.3. Please update your installation of RKWard (or downgrade R). Official debian packaging of RKWard 0.7.3 is available. Packaging for RKWard 0.7.4 is expected to follow, soon.
