You are running an obsolete OS on obsolete hardware. You will continue to encounter internet connection issues that will not be patched with updates. Expect no further updates forthcoming for Catalina, Big Sur or Monterey.


Having said that, it appears you are having trouble launching some apps - Mail and Chrome.

You also say you cannot open AOL. AOL has not had a Mac application for many, many years. You will access that email system via your web browser or email client, e.g. Mail, on Mac.


Restarting the Mac is the first thing to try when troubleshooting.

Have you restarted the computer lately?


If a simple reboot of your Mac doesn’t fix things, see if the problem still happens in safe mode.

How to use safe mode on your Mac - Apple Support 


Safe mode will often correct weird software behavior by forcing the OS to clear caches, do disk repair and other self-maintenance and housekeeping and temporarily disables third-party mods.


Does the same thing happen while in Safe mode?


You can exit safe mode by restarting your Mac normally, then reevaluate the problem.
