A brief guide on how to restore Steam missing downloaded files:

Steam 3.0 for Mac is available as a free download on our software library. Our antivirus check shows that this Mac download is malware free. This free software for Mac OS X is a product of Valve Corporation. The latest version of Steam can be installed on Mac OS X 10.6.0 or later. Steam itself works fine. Fall Guys is a Windows game as far as I can see on Steam so no it won't run. Geometry Dash seems also be an old game from 2014 so I don't think it has 64-bit support. Steam warns for it not being able to run on Catalina or Big Sur. You can still test it because sometime those warnings are false.

Open Steam and click on the Library button at the top of the window. Right-click on the game that doesn't run, and click on Properties. Click on Local Files, then click on Verify the integrity of the game cache. Re-try running/updating the game with the issue.
