    Hi @__Simone ,

    Welcome to Microsoft Q&A!

    Can you create a new project and check if it occurs in the specific project or not?

    I suggest you upgrade your Visual Studio to the latest version from VS installer > Update.
    Then, try to use the command: devenv /safemode to run your Visual Studio in safe mode and check if it persists.

    Sincerely,
    Anna
