    Solved

    I had thought that updating the version of Power BI that I had installed could be fixed, I even completely uninstalled it and started the installation again, for that I did it from the Microsoft store but nothing, the error continued.

    Finally, it occurred to me to download the installer on my PC and that's how it worked.

    I imagine that there was some connection failure while downloading from the Microsoft store since my computer has it connected via wifi (and it is somewhat poor the signal I receive), is the only thing I can think of, anyway, fixed and I leave you the url to download the latest version

    Thank you all anyway.

    Thank you:

    It happens in PB Desktop when you try to open an excel source (it also happens when you try to open a url), select file and when you click load, open PB Desktop and long error.

    I tried to open it with "transform" (using the query editor), here it opens the file but when saving and exiting, it re-displays the same error.
