Hello Adam,
I have helped multiple clients with this kind of issue. This usually means that your code has been detected as "malicious" software.
You say that you are using Electron and this could be problematic; as "older" versions has many security vulnerabilities.
At some point, your account could have been blacklisted; so you could no longer notarize. But during the first rejections, you could still revert it by correcting the issues in your code.
try to notarize a simple "hello world" application to verify that your team is OK for notarization. You could notarize from Xcode or using notarytool
if 1) is working, update your software to use the latest Electron framework and this should solve your issue.
I think that Apple should give a more comprehensive feedback when software is using a problematic "known" framework.
Regards
David
