For Michel,
My answer was truncated by the system. You should try defaults write your_domain NSAppSleepDisable -bool YES
the system erased your_domain in my initial answer

For Michel:
If anyone can tell me how to disable it just for my app under Catalina, I would appreciate it.
You can try: defaults write NSAppSleepDisabled -bool YES
where your domain is defined in your plist as CFBundleIdentifier. Then try defaults read and you should see NSAppSleepDisable=1;
This does not always work if you Hide your app.

The message states that the CoreFoundation frameword is out of sync with the tbd file. Judging from the dates on these two files, the tbd file is much the older.I deleted the tbd file (change the name to oldCoreFoundation.tbd) in both CoreFoundation and IOKit which I was using.Problem gone. It seems that the tbd file is no longer needed at all.John

I reported the missing 13.3 SDK to Apple on 15 December. On 18 December I got a reply: "We are aware of this issue [missing 13.3 SDK] and working on it." App Store update for Xcode 11.3.1 was released on 13 January but 13.3 SDK still missing. On developer.apple.com there is a full release dated 20 December for 11.3.1 but SDK 13.3 is also missing. If Apple are "aware of this issue" it seems they are not really working on it.
