I'm also having this problem and have been a Pandora user for years.
The problem is on my Chrome browser (latest version105.0.5195.125 which I don't think is related). I kept getting an error about the password being incorrect, so I reset the password and it still didn't work. I deleted all the cookies, didn't work. I stopped the adblocker, ghostery & privacy badge (It works fine on other sites), but it still didn't work. The "return" key doesn't seem to work, but I don't know if this is a functional design flaw. I also tried login on from privacy mode with chrome, nope, not working.
I finally used Firefox and the password magically worked. So this is a Chrome specific issue.
I have a Mac Monterey 12.6

I've been unable to log into Pandora through Chrome for a LONG time (used to work fine). I had given up. App on phone worked, so I just lived with it.
I did password reset several times, tried incognito mode...nothing worked on the desktop...until I saw your post and tried Firefox. Worked perfectly fine! I didn't try before because I really thought (hoped, prayed) the browser wars and incompatibilities were a thing of the past.
For the Pandora crew:
I'm running Chrome version 105.0.5195.125 (Official Build) (x86_64), which is the latest as of today, 20220924. I'm running this on macOS Catalina version 10.15.7. Firefox version 105.0.1 (64-bit) works fine.
I regularly encounter this problem, and it's quite frustrating. I get it on Brave (a Chromium-based browser) and in the Windows app (version 184.108.40.206 on Windows 10 21H2). Usually, reloading the page or app allows me to log in.
