I have attched the profile, when the freeze happens, there is output like this:

Start with the attached profile.txt and the VSCodeVim extension-host handling triggered by entering {}, (), or []. Reproduce the freeze and compare profiling output; done means these inputs no longer freeze VS Code for several seconds or make the extension host unresponsive.
