Extension appears to break TypeScript within WSL

[MoonstarCoding]

Type: Bug

Started remote host session in WSL and attempted to develop TypeScript v5.4.5 application. Noticed TypeScript intellisense was infinitely Loading and extensions were not being activated. Usage of Extension Bisect traced down to Regex extension.

Extension version: 0.4.0
VS Code version: Code 1.89.1 (dc96b837cf6bb4af9cd736aa3af08cf8279f7685, 2024-05-07T05:13:33.891Z)

This extension doesn't do anything IntelliSense related. Could you double-check? This might be a random pick by the bisect tool.

After bisect found it, I turned it (and only it) off. It has been 2 full days with no issue ever since. It appears this extension stalls the extension host, preventing any of the extensions from working properly.

Is this when you open a specific source file? Maybe one of the regexes the extension uses is slow on a particular input.

You could also try to get a CPU profile in F1 > Developer: Show Running Extensions and there right-click the Regex extension and Start Extension Host Profile.

To answer point 1: It occurs on any project that has a node_modules folder and more than one TSX file. I couldn't recreate when it was just one though.

To address point 2: due to it having been on my work laptop and crashing the application, I was forced to uninstall it and it is now a black listed plugin for causing this issue reliably on 4 separate work devices. So reinstalling it is not an option. Even if I could, my work network blocks the upload of files with specific extensions, and I have trouble believing one with .cpuprofile would be sanctioned. So I can't help you with this.
