Sequoia 15.4 refusing to open files - possible malware

I just updated to 15.4. Trying to open a simple text file (with srt extension) pops this up: "Apple could not verify" xxxx.srt "is free of malware that may harm your Mac or compromise your privacy." Some other srt files open fine.


This is a dealbreaker for me if I can't disable this "feature". I know I can go burrowing into settings and exempt this one file. No. How do I turn off the whole thing?

I found a fix: https://disable-gatekeeper.github.io/

The fact that a system designed to prevent users from launching applications is also blocking text files suggests it is not well designed.

This file extension change workaround does not work at all on my computer with 15.4.1, where the problem still appears.


I am almost sure the cause of this problem lies in the app where the .srt file was created.


Each app has attributes that are inherited by the resulting files, and I believe all we need is some user here who could tell us how to identify the attribute(s) leading to the original app, so we could let the developer know he or she has to contact Apple to fix this issue.
