I get this message when installed from brew:
“VSCodium.app” can’t be opened because Apple cannot check it for malicious software..
There is no usual "OK I'm fine with that" button in the preferences/security&privacy :(

An additional comment: after using the standard code . command, I realised that it's now VSCodium, so using command line, it starts properly.
@mudlee for now you'd have to "right click" the App and then hold the alt/option key, while clicking "Open" (only on first launch I think)
command$ code
still an issue.
Running the following solved the issue for me:
codesign --sign - --force --deep /Applications/VSCodium.app
xattr -d com.apple.quarantine /Applications/VSCodium.app
Running the following solved the issue for me:
codesign --sign - --force --deep /Applications/VSCodium.app xattr -d com.apple.quarantine /Applications/VSCodium.appdeleting quarantine only solved my problem.
xattr -d com.apple.quarantine /Applications/VSCodium.app
I found that if you go to Applications-> RightClick-> Open it works. And its only required to be done the first time.

This worked for me. And to confirm, it is only for the first launch. Thank you!

Worked for me as well. Thanks for the workaround!
