vscodevim stopped working sometimes until reinstalling the extension

Describe the bug
I am using the web version of vscode (i.e. code serve-web ...). Sometimes vscodevim just stopped working. The developer console would have these log:

2024-07-15 10:22:59.268 [info] Extension host started
2024-07-15 10:22:59.620 [info] Eager extensions activated
2024-07-15 10:22:59.638 [info] ExtensionService#_doActivateExtension vscodevim.vim, startup: false, activationEvent: 'onStartupFinished'
2024-07-15 10:22:59.665 [error] Activating extension vscodevim.vim failed due to an error:
2024-07-15 10:22:59.665 [error] Error: Not Found
	at R.xb (../../../vs/workbench/api/worker/extensionHostWorker.js:111:53700)
	at async Promise.all (index 0)
	at async n (../../../vs/workbench/api/worker/extensionHostWorker.js:96:6385)
	at async n.m (../../../vs/workbench/api/worker/extensionHostWorker.js:96:6348)
	at async n.l (../../../vs/workbench/api/worker/extensionHostWorker.js:96:5805)

This issue won't go away when I reloaded the browser window or restarted the code server. It did go away if I re-installed the extension and then reloaded the window.

To Reproduce
I don't know how to repro this. It just happenes sometimes.

Environment (please complete the following information):

Extension version: 1.27.3

vscode:
Version: 1.91.1
Commit: f1e16e1e6214d7c44d078b1f0607b2388f29d729
User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/126.0.0.0 Safari/537.36
Embedder: server-distro

OS: linux (debian)

Start with the web VS Code setup (code serve-web ...) and the extension-host activation logs showing vscodevim.vim failing with Error: Not Found. Investigate the extension activation path and compare a normal installation with one that requires reinstalling; done means identifying a reproducible cause and confirming the extension activates without reinstalling.
