Hi,
Thanks for confirming this. It looks like an IntelliSense-related error, so please first check if the project builds successfully.
Then try creating a new project from scratch (ensure it uses the same make/cmake tool) and check if the problem persists.
If the problem does not affect build, please try clearing the VisualGDBCache and CodeDB folders when the project is closed and then reopening it. If the problem affects build, please try comparing your project settings with a newly created project that builds.
Finally, if you cannot create any project at all, please try reinstalling the ESP32 toolchain, as it might have gotten corrupt.
