Code signature becomes invalid after a few months

[nettybun]

The OS thinks Kap is malware after a few months. Is it possible the code signature would become invalid due to a self update? I saw other issues about "could be malicious software" but I did the "Open Anyway" dance back in Nov, so I thought that would register the code signature properly.

Here's the system information view which shows the signature:

macOS version: 12.3.1 Kap version: 3.4.2

Steps to reproduce

• Install Kap 3.4.2 in Nov 2021
• Wait a few months til June 2022
• Suddenly code signature is invalidated?

Current behaviour

Sigkill.

Expected behaviour

Code signature continues passing...

Workaround

Reinstall Kap. In this case, to latest 3.5 version.
