Problems with Lightroom and Photoshop MacOs10.13.6

[#1]

Hello, I'm having problems with Lightroom on my Mac. When trying to open lightroom, the operation starts well, but right after the opening screen is mounted, the software locks and closes automatically. I also have a curious fact in Photoshop, I can't export files ("export to the web" function. It ends with an error message unknown to the operating system. Can anyone help me? Or someone who has had a problem like this?
I work with MacOs 10.13 .6 I just hope it's not a problem with my old operating system.
thank you.
