App won't launch - illegal hardware instruction

[TheGorf]

MacBook Pro (13-inch, 2019, Four Thunderbolt 3 ports)
Version 11.6.1 (20G224)
2.8 GHz Quad-Core Intel Core i7
16 GB 2133 MHz LPDDR3

I installed via both Brew and the direct download link. Both produce the same situation. When you click on the app I get the initial warning about launching an app from Github. But then it closes. Any further attempt to launch the app is unsuccessful. When I attempted to run it from command line I get:

gorf@a483e79bebab ~ % /Applications/Overkill.app/Contents/MacOS/Overkill
zsh: illegal hardware instruction  /Applications/Overkill.app/Contents/MacOS/Overkill

I tried to run "trace" on the app, but it produced the error "WARNING: One or more duplicate entries found in your codefiles, which will lead to unpredictable decoding behavior. Re-run with -v for more info" so apparently it isn't as easy as it is on Linux. Happy to troubleshoot this with some guidance. I suspect #25 is probably the same thing.

There are a number of other pages reporting similar errors with the illegal hardware instruction.
