I updated my MacBook Pro to Catalina yesterday and every time I login, it kicks me back to the login screen after a few seconds or minutes. I did not have this problem prior to the update! HELP NEEDED!

Hmmm.

If your Mac doesn't start up all the way

You can try a Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5-15 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc. Login and test. Reboot and test as caches get rebuilt.

In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.

If no resolve you can try reinstalling the Combo update macOS 10.15.4 https://support.apple.com/kb/DL2037?locale=en_US

on top of your existing macOS.

If still no resolve you can fall back to your previous macOS and try again—

Thank you so much! When my Mac updated to Catalina, "Hot Corners" were automatically turned on. I had no idea what "Hot Corners" were. LOL.

Thanks for your report feleciaNOLA—

Glad to hear you got it sorted.
