R Notebook has stopped autocompleting object names and commands

I opened R Studio today to continuing working in an ongoing analysis notebook and discovered that whilst working in the notebook R Studio has stopped autocompleting and autoindenting. Autocomplete still works in the console pane, but it no longer suggests objects when I write code in chunks in the notebook. I have checked in Tools > Global Options > Code > Completion that completion options are turned on and in Tools > Global Options > Code > Editing that the auto-code indentation is turned on. I have uninstalled and reinstalled both R and R Studio and the problem is still persisting. I am using R Studio Version 2024.09.1+394 and R version 4.4.2. Has this happened to anyone else? And does anyone have any suggestions for a fix?
