Visual Studio doesn't show vue.js/npm project files

Question

I've been trying to load an asp.net solution which includes a Vue.js client in visual studio (2022), the problem is that while visual studio opens correctly all the various projects inside the solution, the vue js project files are not shown and only a file named "npm" appears (see image below), I've tried several ways to fix this but nothing seems to work. Does anyone know why this behavior is happening? Thanks in advance.
