Apps from App Store Crashes straight after start.

Hello, I have some wierd problem with my MBP 13 Early 2011 model on High Sierra OS. Yesterday I got all of my apps downloaded from App Store crashed during start. All of my attempts are ending with this example crash report:



I will only add that this occurs to all applications such as Messenger, Whatsapp etc. Wipr is just an example. Reinstalling the system did not improve the situation. The diagnostic process shows no problem Can someone describe the source of the problem?

MacBook Pro 13″, macOS 10.13

I have the same issue as well as many other people. The issue has been reported in eight different discussion threads that I know of.

Observed behaviour is:

Almost all apps downloaded from the Apple App Store crash with a 'Code Sign Invalid' error (CODESIGNING).


It's not conclusive, but the issue seems to...

...have started around Wednesday last week (2020.11.11);

...affect macOS High Sierra (all versions, unpatched and patches);

...affect systems that have had the operating system recently reinstalled.
