Kerbal Space Program

When launched from both Steam or command-line, the application hungs at the very begining of the loading.

This bug occurred with version 1.10. I never had it before (v1.3, 1.4, ..., v1.9.1 always worked).
This bug is systematic. (Thus: I can't play anymore :-( )

Machine is up to date:
macOS Catalina v10.15.5

I am available for further investigations/testing.

Here is the console output when launched from command line, with unusual Stacktrace:

$ ~/temp/Steam-temp/steamapps/common/Kerbal\ Space\ Program/KSP.app/Contents/MacOS/KSP
[S_API FAIL] SteamAPI_Init() failed; no appID found.
Either launch the game from Steam, or put the file steam_appid.txt containing the correct appID in your game folder.
