f12 "go to definition" does not work in CPP files with CPP and React/js extentions installed.

[timbo100]

Describe the bug
The problem appears to be in one project where I have mixed javascript/react extensions plus CPP extensions installed.

Other CPP project that don't have javascript/react extentions installed have no issues with goto definition action in CPP code.

In the problematic project which has javascript/react code files, I am able to use goto definition between javascript files. However, when I'm in a CPP file goto definition action results in "no definition found..." alert.

Please confirm that this problem is VSCodium-specific
I have opened same projects with vscode and made sure I have same named extensions also installed. The vscode app has no issue with goto definition from either CPP or javascript files. Each takes me to file I have focus on. For example I'm choosing the imported files (Js) or included file (cpp) to test.

Please confirm that the issue/resolution isn't already documented
I've searched issues with no results that involved to types of source files.

To Reproduce
Steps to reproduce the behavior:

1. create a new project (~/myprojects/proj1) with CPP files that are in compilation closure of main.cpp, e.g.
2. from ~/myprojects/ use npm create vite@latest proj1 -- --template react to merge a beginner react project with js code into existing proj1 project
3. add extensions: Prettier - Code formatter; ES7+ React/Redux/React-Native snippets to proj1, as well as typical CPP useful extensions.

Expected behavior
vscode editing of proj1 gives me expected behavior:

1. when I choose inclusion file at the top of main.cpp and select F12 the included files opens in a new tab
2. when I choose import, e.g. of App.jsx in main.jsx and select F12 file App.jsx open in a new tab

Additional context
I tried disabling the js/react related extensions in the problematic vscodium session and then restarted vscodium but it didn't make a difference. goto definition for jsx file worked but CPP didn't.

Some additional information that might be useful:

Even though I have vscode installed I like vscodium and continue to use it without goto definition working.

One thing that I noticed just now is that when I open my CPP only project with vscodium, the output window appears to show what appears is reevaluation of the CMake scripts, which takes about 10-15 seconds. And of course I'm able to goto definition fine on that project. However, when open the project with javascript and CPP code, I get the following in the Output window of vscodium:

Error: there is no registered task type 'cppbuild'. Did you miss installing an extension that provides a corresponding task provider?
Error: there is no registered task type 'cppbuild'. Did you miss installing an extension that provides a corresponding task provider?
Error: there is no registered task type 'cppbuild'. Did you miss installing an extension that provides a corresponding task provider?

I'll start looking for what this might be but it's not immediately familar.

Thanks

I have the same problem, I cant jump to definition by pressing f12. Right click don't show the option either.

The only addon i have installed is clang-format
