Description
Thank you for a great extension!
Describe the bug
None of the movement keys (haven't checked other keys) were working for several seconds as if the window froze. I see several errors in the dev console:
INFO Extension host (LocalProcess pid: 88104) is unresponsive.
localProcessExtensionHost.ts:273 Extension Host
localProcessExtensionHost.ts:274 Debugger attached.
log.ts:421 INFO UNRESPONSIVE extension host: starting to profile NOW
log.ts:421 INFO Extension host (LocalProcess pid: 88104) is responsive.
log.ts:421 INFO UNRESPONSIVE extension host: received responsive event and cancelling profiling session

Research direction
Start with the stack trace in the issue, especially the movement path through prevWordStart and getConfiguration, and inspect the extension-host profile if it is available. Reproduce the freeze on VS Code Insiders 1.85.0 with VSCodeVim 1.27.1, then identify and verify the configuration-related cause; the report currently provides no reproduction steps or source-file path.
