Unable to open app on M1 Mac & Big Sur

I'm unable to open 0.3.5 or 0.4 beta on my M1 Mac. I get an odd error related to permissions

According to this link the problem has to do w/ the way the dmg was compiled

Just found out that it works when I install from the app store... just not from github...

Same here -- v0.3.5 from App Store worked fine, but the v0.4.0-beta DMG from this repo throws that error.

The crash report reveals the cause as Code Signature Invalid and a termination reason as Namespace CODESIGNING, Code 0x1, so that suggests it's not an architecture problem as is suggested in the link @johntdyer shared.

Executing codesign -v "/Applications/MQTT Explorer.app" doesn't return any validation errors, and neither does spctl -a -vv "/Applications/MQTT Explorer.app", so it doesn't appear to be a problem with expired signing certificates.

Looks like the app package might have been tampered with, which invalidated the signature.

Workaround (warning, security problem, don't do this):

I removed the signature with codesign --remove-signature "/Applications/MQTT Explorer.app" and was able to launch the v0.4.0-beta downloaded from this repo.
