The above part of the message has a white background and it is front of a screen with a blue background. The part of the background message I can read references more than one error codes; but the complete message has the white pop up message in front.
So I'm not able to read all of it. Close to the beginning of the message on the blue screen says Windows Defender Error Code: 0x ....then I can't read the remaining numbers as they are behind the white screen.

I haven't shut down my computer, but I ran task manager and ended the task. I'm now signed into the Firefox browser on my PC. I'm afraid to sign back into Internet Explorer. Help.

That's a fake so-called Tech Support scam alert/warning which you are seeing in your browser.

"Remember that real error messages from Microsoft, or other big tech companies, never include phone numbers for you to call them.

If your screen suddenly fills with scary pop-ups you should immediately close your browser (try pressing ALT+F4 if you can't do it with your mouse). If you can’t close your browser try restarting your computer."
