Steam application will not open after catalina update

Steam (software hub for video games) fails to launch after Catalina update. I hadn't opened it in a while. But when I did, it just bounced in the task bar for a few seconds, then stopped. No error message even! What is going on? I tried restarting, deleting & reinstalling... no success. Help plz. Thanks.

App Store not opening after the latest Catalina update on MacBook pro Hi, I just updated my 2012 MacBook Pro to the latest version of Catalina and the App Store won’t open. It just gives the loading beach ball and won’t open when I look at the app in the task bar it shows application not responding. .it was working fine before the update. I have tried everything and nothing works. I have tried to change the date, restart the app and restart the computer. Does anyone know how I can get the App Store working again?

Catalina: Apps bounce, but never launch I recently upgraded to Catalina 10.15.3 from Mojave. Since then, I've noticed that after the computer has been running for a while, apps won't launch from the toolbar. They just start bouncing, but never come up. Restarting the computer fixes the problem, for a while. Anybody find a fix for this? This is on a 2019 MacBookPro 15".

You'll have to update the steam app. Here's the link https://support.steampowered.com/kb_article.php?ref=1055-ISJM-8568
