Hey, @gailh96161217. Welcome to the Photoshop Community. I'll need more info to help you figure this out.
I’ve moved your post to Questions for now. Please share more details, such as the version of Photoshop, and the operating system, along with screenshots, and video recordings of what you see.
At this point, the given information is too limited for us to help you.
Thanks! Sameer K

If Photoshop doesn't start correctly or doesn't run, try to reset the Photoshop preferences manually. See here Preferences in Photoshop and scroll to section "Reset Photoshop preferences". Near of the end of the document you'll find how to reset the preferences manually.
