[vs-code-engineering]

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.104.1. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

The two screenshots were taken in the same project on two different versions of VSCode The only difference is the VSCode version all plugins are identical

[dreward]

It is the latest version that causes the problem

[eleanorjboyd]
