Symlink does not open to me in any way

Hello, I am trying to start the simlink and it does not work for me, I have already done everything I put in the forum, delete it as indicated in the steps, restore to a previous version of windows, and nothing, it still does not work, what if, is that the last time he let me start it, I changed a proxy option, I don’t know if that will have something to do with it so that it won’t let me run the application.
Please wait for an answer.
Thanks
