The issue is fixed in the latest version of Big Sur. Be sure to upgrade. It’s being exploited in the wild.
Compare "Gatekeeper" fixed issues here:

Feels for me that they only patched one part of it on Catalina but gates are more open on the older macOS. Really don't like that.
This is a technical crowd, so some of us don't need to rush to download things like this. I'll upgrade when it's convenient, thank you very much.
I am grateful for the "upgrade now" message being pushed it. As a technical user I can't trust my skills and knowledge to truly keep me safe from this one.

I personally kept both Gatekeeper and SIP turned off, back when I used modern macOS. But if they are turned on, they ought to work.
Or do you also have to install the profile after you tell it to get out of your way?
And it's not just a matter of protecting you against out-and-out malware (although that's certainly part of it), it's a matter of protecting you against developers whose interests don't entirely align with yours. Developers who really want to spy on their users seem to be the biggest group (see, for example, the recent Apple vs. Facebook kerfuffle).
Unfortunately, distrusting software does add friction, especially if you add (/update-via-unsupported-mechanisms) new software frequently. "Are you sure you meant to run this program? It looks weird to me; I think you should get rid of it. Should it really have access to your contacts/camera/etc?" macOS is acting a little like an overprotective parent here, and it's certainly annoying. But the threats it's trying to protect you from are real. You can turn the protections off (with a certain amount of work), but then you're vulnerable to all the stuff it's there to protect you from.
P.s. I don't mean to completely defend Apple here. Their preferred solution is to have all software distribution go through their App store... where they get a cut of the price. Which means they're also on the list of developers whose interests don't entirely align with yours.
I told macOS to run that program because I trust it. If macOS trusts me then it transitively trusts the program I told it to run.
In other words macOS doesn't trust me to validate programs before I try to run them.
The keyword here is sometimes This is what I Love about current state of MacOS.
To fix it nothing works until you delete it completely and only then if you lucky etc ... It just reminds me those old good days with Microsoft many years ago. Turn it off then turn it on few times .. it may work ...
Thankfully there is a simple workaround: https://hiringengineersbook.com/post/disable-quarantine/
( I always prefer to see the extensions too though :) )
That’s not exactly an answer to your question, but there’s a chance it’s an acceptable solution, so duly noted.
Finder does try to help with renaming and when you try to rename a file only the filename is selected and not the extension.
I remember once installing several of his apps, but then coming to the conclusion that i don't know enough - even though he consistently seems to find and fix flaws in OSX.
Why isn't Apple hiring this man?
EDIT: Why are people downvoting this question? If i'm implying something then i'm unaware of it.
This time, he told Forbes that "the hacks effectively take Mac security back a decade" [1], and Vice quotes him as saying "this is likely the worst or potentially the most impactful bug to everyday macOS users in recent memory". [2]
Forbes ran the story with the headline "The ‘Worst Hack In Years’ Hits Apple Computers", and that's bullshit.

Overcomplicated and bloated security features, telemetry, iOSification of the UI, dumbed down settings, bugs..
Perhaps the time has come to shed some legacy and restart again from scratch (like Google Fuchsia) or to invest some of the hundreds of billions they have in refining the software so it actually works
