@DevXstyler Can you give more info? What have you tried to activate it? Are there any errors logged?

@sean-mcmanus Hey, so I tried re-opening VSCode, Restarting my PC, reloading the window, deleting the extensions, disabling and just activating them but nothing worked. I tried around for a bit and found out I had to manually delete the folders for the C/C++ extentions in the VSCode folder, only then it worked. I tried different extensions but it seems like this is the only one.

@DevXstyler You mean the bug only reproed with 1.30.5? What about 1.30.4 or 1.31.0 (pre-release) or later? Our extension is not responsible for activating itself, so normally this would be a VS Code bug unless we are activating but failing during our activation. What logging related to our extension activation do you see? If you don't see any logging, that would imply VS Code itself is not activating our extension.
