Cannot execute CodeLens command using the "Show CodeLens Commands For Current Line" command: "actual command NOT FOUND"

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.63.2 and 1.64.0-insider
• OS Version: Windows 10 Enterprise 21H2 Build 19044.1415

Initially I found this issue on the Azure Stream Analytics extension, but I can also reproduce it on the CodeLens Sample extension which I think should provide a simpler environment to debug.

Steps to Reproduce (Using the CodeLens Sample extension):

1. Clone the project source: https://github.com/microsoft/vscode-extension-samples
2. cd to the codelens-sample directory;
3. npm install then vsce package;
4. Install the generated extension package codelens-sample-0.0.1.vsix;
5. Open any file, the above extension provides CodeLens command "Codelens provided by sample extension" on every line;
6. On any line, use Ctrl+Shift+P, then "Show CodeLens Commands For Current Line";
7. Choose the CodeLens command then hit Enter;
8. VSCode will show the below pop-up windows on the left-bottom corner;

9. If we try step 6 and 7 a few more times, it will work eventually.

I see @jrieken resolved an issue #84153 which reported the same error message. So I also tried to debug this issue in the Developer Container. This issue is also related to the CodeLensCache, the cache key doesn't exist in the CodeLens cache. I'm not familiar with how the CodeLens cache works so the debug stuck here. Could you please help take a look? Thanks a lot.

I can reproduce in insiders but not when running out of dev. This error happens when code lens results are being disposed and that usually happens after a model or config change (anything that re-requests code lenses).

Thank you so much for the quick fix. I've verified it works well in VSCode Insiders.
