Describe the bug
Right after VS Code startup, executing a command that is not repeatable by . (e.g., :w, :q) and then pressing . twice causes the extension to stop responding until the window is reloaded or restarted. This was found while working on #9807.

To Reproduce
Steps to reproduce the behavior:

1. Launch VS Code with VSCodeVim enabled.
2. Execute :w (or :q — any command not repeatable by .).
3. Press . twice.
4. Observe that the extension becomes unresponsive (no key inputs recognized, etc.) until reload/restart.

Expected behavior

• Pressing . after a non-repeatable command should be a no-op (or repeat the last edit if any).
• The extension must not freeze or enter an invalid state.

Screenshots

Environment (please complete the following information):
