I've been using Visual Studio 2019 with only C# desktop development and to type "public int" I pressed p, u, [space bar], i, n, [space bar], and that was all.
After installing Node.js development, I have to press down arrow key and select by pressing Enter.
In short, the autocomplete suggestion is now not being applied by pressing the space bar.
Is there any preference setting that can change the way autocomplete works or will uninstalling the Node.js/Javascript environment fix the problem?
