The menu bar is gone.

One day, Photoshop 2019 was gone from my laptop.  Not, like, "it wasn't working."  It was *gone.*  Fine, okay.  I went to download Photoshop again.  

What happened was Photoshop 2020.  

At age 30, I'm a cranky old man (...fine, I'm a girl) and I'm not loving things being different.  Where's my paint bucket?!  (I found it, nbd.)  Why's stuff all weird?  Gah.  I just want a static version of Photoshop, man.  I never needed CC to happen.  Oh, well.

The menu bar, however, is gone now, and this is a problem that I cannot work with.

Before anyone asks, I have updated all the drivers, restarted the computer, and still have the problem.  Microsoft Windows 10 home.  I googled the problem and found a lot of PRESS THE "F" KEY! advice, which does not correct the issue.
